Simple watercolor painting using candle wax

Candle wax can be used to protect the highlights or white passages in your watercolor painting. I have used it to create the impression of waterfalls, white foam on the sea, and to save highlights on rocks. This simple watercolor painting using candle wax was done with only a few colors and some quick watercolor washes. It is one of the early exercises I have all my beginner watercolor students do.

The trick with using candle wax is to understand the surface of your paper and what effect you are trying to produce. If you press lightly, less wax will be deposited on the paper surface. If the paper is textured, rather than smooth, you will get a broken edge of white unless you press very hard. The easiest way to learn the properties of wax on watercolor paper is to try it. Any experimenting you do on various papers and candle sizes will be beneficial.

The wax creates a barrier on the paper surface so that it stops the paint from sticking to its surface.

The one big negative about using wax on your watercolor paper is that it is permanent. You can’t remove it and you can’t paint over it. So you have to really need or want to use it and you have to know exactly where you want to place the wax.

Materials for using wax on watercolor paper

  • Arches 300gsm Cold Pressed (also known as Medium) watercolor paper, eighth sheet (approx. 7.5″ x 6″ (19cm x 14cm).
  • Brushes: Round — Sizes 24 and 12 for larger washes and 8 for the smaller areas and detail.
  • Paints: All Winsor and Newton — Cobalt Blue, French Ultramarine, Raw Umber, Burnt Sienna, Permanent Alizarin Crimson, Cad Orange.
  • Backing board
  • Masking tape
  • Old towel to control wetness of your brushes
  • Pencil, tissues, and large water container that holds about 3 pints.
  • Clear (white) candle

Drawing

I did a very light drawing of where the rocks would go.

Watercolor under painting

Before laying down my first wash I mixed my sky colors in my palette. The colors used were Cobalt Blue with a touch of Permanent Alizarin Crimson, Permanent Alizarin Crimson on its own, and some Cad Orange on its own.

By premixing my starting colors I can paint the big washes very quickly.

I start my under painting with the Cobalt Blue and Permanent Alizarin Crimson mix. I lay this wash down at a bit of an angle so that the sky does not have a horizontal look. Your brush must be fully loaded with paint. (A fully loaded brush is one that if you hold it vertically, with the point down, it will drip.)

Each wash of watercolor paint must be wet enough that it easily flows down the paper and forms a bead of paint at its bottom. You have to paint it very quickly or you will get streaks in the sky.

After you lay the first wash down, quickly load up your brush with the Permanent Alizarin Crimson and run this along the bottom of the blue wash. I run my brush about a quarter to a half brush thickness from the bottom of the first wash. You have to paint each wash fast enough that you can see the watercolors flow down your paper. If you are not seeing this then you are not loading up your brush with enough paint or you are moving the brush too slowly.

Repeat the above with the Cad Orange mix down to the distant horizon.

I then added some French Ultramarine to the blue mix in my palette and used this to paint the water down to the sand which was a just Raw Umber.

The sea area was a bit weak so I added more pigment while the painting was still wet to strengthen the sea color. I then dropped in a much stronger mix of the sea color under the wet waves.

I let the under painting dry thoroughly at this stage!

Once the under painting was totally dry, I painted the rocks with a mix of French Ultramarine and Burnt Sienna. While the rocks were still wet I used a clean damp brush and softened the edges that touched the sand — ­quite often you will see damp sand, even little pools, around the edges of rocks near the sea.

The painting was completed with the addition of a few squiggles on the sand to represent sea weed or other flotsam and jetsam that ends up along the shore. In this case the squiggles are used to break up the sand area into more interesting shapes.

This type of painting can be done very quickly and is a good exercise for teaching beginner watercolor artists how to handle quite wet washes.

The birds would probably have been better left without the wax and then just placed in later with a dark color or white gouache.

Watercolor painting demonstration – Pughs Lagoon

The subject of this scene is really the early morning light on the grassed hillside. Pughs Lagoon is about 30 minutes from my home and a popular site for local artists. This painting was done en plein air and, as I was quite happy with the result, I thought I would go through the steps I took to complete it.

Because of the rapidly changing light, these situations require quite fast painting and a clear idea of the steps you need to take to capture the subject – in this case it was the light. I was at this same location the week before so I already had a good idea of the painting I wanted to create before I arrived.

Drawing and watercolor under painting

My sketch was kept light, focusing on the two buildings and the water line. I also indicated where the two major tree groupings would go. The trees were not drawn in any detail. As I was focusing on the light on the hill, I placed the waterline at about 20% up from the bottom of my watercolor paper.

Once the drawing was done, it was then time for the under painting. Notice that I kept the lagoon area dry. You cannot do this section until the rest of the painting is done, otherwise you would not know what to put in the reflections.

The watercolors I used for the under painting were Cobalt Blue and Cad Orange for the sky. Both were mixed with a lot of water as they would make up the lightest section of the painting. It is better for the sky to be too light than too dark. Winsor and Newton’s Cad Orange is a very yellow orange and is used with plenty of water or it will appear opaque. If your orange is too red, like with the fruit orange, it may be better to use Yellow Ochre instead.

The greens were mixed with various mixes of Cobalt Turquoise, Aureolin and Raw Umber for the lighter passages. A small amount of French Ultramarine was added for the darker ones. Here and there I also used a touch of Burnt Sienna.

As you can see, all the edges in the sky, tree and hill area, apart from a few left highlights, are all soft. This means they were painted wet on wet.

The paper was not pre-wet.

The sky was painted all the way down to the water’s edge, though with a lot more water in the mix in the hill area. I then immediately went in with the tree and grass under painting. It was the wet sky wash that gave me all the lovely soft wet on wet edges for the trees and grass.

The angle of my easel was at about 40 degrees. When I paint outdoors I keep my board at a steeper angle to allow me to paint with less water. The steeper board angle lets the watercolors flow as they would with more water but at a lower angle. This allows me to keep my paper a littler drier while still creating the same effects I can produce in my studio work. As I don’t have access to a hair dryer when painting outdoors, the drier I can keep my paper the faster it will dry fully so I can move on to the various stages of my painting. It still has to be wet enough for the watercolors to flow however.

I let this stage dry totally – both the paint and paper.

Painting the trees and shrubs

With the under painting totally dry it was time to paint the trees, shrubs and buildings. Starting on the left with the trees, I moved from left to right also painting the buildings as I moved along. The trees and shrubs were painted with the same colors as those used for the underpainting, though with varying mixtures of paint. Less water was used, creating thicker mixes to strengthen the tones, which allowed the trees to be contrasted from the grass on the hill.

The sides of the buildings were painted with a very weak mix of Yellow Ochre, Burnt Sienna, and Cobalt Blue. The building in the distance had a little more blue in the mix as it was further away. The chimneys were painted with Burnt Sienna and Permanent Alizarin Crimson. The colors for the roof were French Ultramarine and Burnt Sienna. The distant roof has more water in the mix to push is further away in the picture plain.

As I continued to work from left to right ­­- right to left if you are right handed – I kept varying the colors and tones used, to create an interesting composition. I took inspiration from the view in front of me but I was not constrained to place everything where I saw it. My main intention was to create an engaging work of art, not a replacement for a photograph.

Painting the Shadows

Once the trees and the building were completed I quickly added the shadow shapes. These not only anchored the objects to the ground but were critical to giving the painting its feeling of bright morning light. My shadows were painted with a mixture of French Ultramarine and Permanent Alizarin Crimson; the mix has to lean towards the blue not the red however.

In a couple of areas I had splashed on (with my brush) some clean water. In this way, when the shadows were painted, they produced some nice soft edges as they hit the wet spot. Make sure your shadow color is already mixed before you splash on the water, or else it will dry before you start painting your shadow, thus defeating its purpose.

 Painting the water of the lagoon

The water was painted with the same green colors with a touch of Burnt Sienna to grey them off.  Reflections on water are always a little duller than the objects being reflected. I used this time to sharpen the shapes of some of the grasses on the water’s edge with mixes of Burnt Sienna, Permanent Alizarin Crimson, and French Ultramarine. Remember to make your reflections directly below the object being reflected, and towards the bottom of your paper.

Finishing my plein air watercolor painting

I let the lagoon area dry thoroughly, and then painted the final details. These included the birds and logs in the water along with their reflections. I also added a few clumps of grass on the hill and a small leafless tree near the buildings. I make sure not to overdo this however. Objects such as these are placed only with balance and composition in mind. Just because something is there doesn’t mean you have to include it or that you can’t move it.

I hope this watercolor painting demonstration may inspire you to get your paints out and go plein air painting as well.

Plein air watercolor landscape painting

Here is today’s plein air watercolor landscape painting I did with my Thursday plein air group. The location is in Luddenham, a semi rural area just outside of Sydney, Australia. It was a lovely day to be painting outdoors. Warm but not too hot, few clouds so no moving shadows to contend with, and no wind – perfect!

I was immediately drawn to an old shed in the distance and the pattern made by the trees around it. The form of the hills would allow an interesting lead into the focal point – the shed. While the distant hill would add space to my painting.

Here is the scene I was confronted with.

The steps I took for this plein air watercolor landscape painting are as follows:

  1. Decide what attracts my attention in the vista along with any compositional changes I will make. Remember there are no rules that say you have to try and paint everything you see when painting outdoors. I try to work out what is the minimum I need to put into my painting while still achieving the message I want to present. Too much information can lead to a confusing message.

I set up my plein air watercolor painting kit which you see below. Because the sun was already quite high in the sky I used my umbrella to shade my watercolor paper and as much of my palette as I could.

The umbrella is supported by a lightweight extendible pole and attached to my plein air easel with Velcro tape. I used my carry bag as a counterweight as my plein air easel is very light and the umbrella could have toppled it. The bag hangs on the other end of the aluminium arm that supports my little folding palette.

Now that I am all set up I do a loose drawing of the scene. I am mainly interested in the general layout of shapes when doing my drawing. I do not put in a lot of detail as I want to keep the whole watercolor painting free and loose.

With the drawing done my next step is to paint the sky and the ground under painting. It is very important that you get your tones right for this stage. The sky is usually the lightest tone in the landscape. The ground should be lighter, cooler, and softer in the distance. It’s tone increases as it moves towards the foreground where warmer colors are used. At this stage of the watercolor painting it should already look like a landscape, with the sky and your ground almost finished.

The greens I used for the ground are made up of various mixes of Aureolin, Raw Umber, Cobalt Blue (only a little) and French Ultramarine. All these water colors a artist’s quality and made by Winsor and Newton.

I take this opportunity to have a coffee and a chat while waiting for this stage to dry thoroughly. If you try to keep painting without letting the watercolor under painting dry thoroughly you risk creating mud.

The painting is now well on the way. Next comes the trees and the shed. I made sure the distant tree line was lighter in tone to those around the shed.

The shed is painted with a mix of Cobalt Blue and some Burnt Sienna to create a grey.

The rust on the roof is created with Burnt Sienna and very little water. I used the side of my round brush and barely touched the paper. This creates a dry brush effect.

This plein air watercolor landscape painting was now nearly finished. All I had to do was put in the details, the pond, cows and fence lines. These objects are all placed to help the composition. Even the birds in the sky are placed to add interest and depth to the sky. They also help direct the viewer’s eyes to where I would like them to go.

The painting is finished and signed. The finished painting is below. If you have any questions please do not hesitate to let me know either through the comments section below or better yet through the forum pages.

Watercolor Painting

What is watercolor painting? If you tackle the subject from the point of view of painting with colored water, rather than watercolor paint you may find it easier to understand.

By considering watercolor painting as dealing with colored water you are forced to give more thought to the water component. Water is the most important ingredient in watercolor painting but it is rarely given much attention. It is the water that lets watercolor paint do its magic.

I have found that most of the difficulties new watercolor artists run into are related to not keeping an eye on what the water is doing. On their painting surface or in their palette or on their brushes. Sure part of the problem is confusion about what steps to take with their painting, however as this confusion slows down their response to their work which allows the surface to dry too fast – hence water becomes a problem even here.

Why water is critical to a successful watercolor painting

It is the flowing of water and pigment on your paper that leaves behind a nice clean layer of paint called a “watercolor wash”. If you do not use enough water in your paint mix it will not flow down or over your watercolor paper and you will have a rough looking paint layer. In fact this is often what people refer to as a muddy watercolor painting. It is muddy not because it is the color of mud but because the layer of watercolor paint on the surface of your painting is actually quite rough instead of smooth which is what happens when enough water is used in the mix. This rough surface seems to inhibit the transfer of light through the watercolor layer. If you run your fingertips over a muddy passage in your painting you will find that it feels rougher, than when compared to a nice clean passage of your watercolor painting.

Think of sand on a beach. If the sand is roughed up by people walking, digging, or otherwise playing on it while it is damp, it will remain roughed up. However if a wave rolls over the sand as it washes back out to sea it leaves behind a nice smooth surface. This is similar to what happens on the surface of your watercolor paper. A definition of watercolor mud was given by a famous Australian watercolor artist, Norman Lindsay, who compared the process to that of a muddy puddle. If you leave a muddy puddle undisturbed, as it dries, it will leave a nice smooth finish. If however you disturb the mud while it is still damp, for example by digging into it with a stick, it will dry with a rough surface. This again is very similar to what happens on the surface of a watercolor painting if you keep trying to paint with thicker paint on a barely damp surface.

How much water to mix with watercolor paint

So just how much water should be in a watercolor mix? Well this depends on a number of factors:

  1. The angle of your supporting board. The steeper the angle the less water is needed to allow the paint to flow.
  2. How fast you paint. This is connected to your skill and experience level. The slower you paint the wetter your watercolor paint mix should be so it doesn’t dry too fast and stop flowing.
  3. How wet your watercolor painting is from a previous wash. Painting with thick paint into an already wet surface will still give you a soft edge but it will be more controlled than when you paint in a wet surface with a very wet mixture.
  4. The tone (relative lightness or darkness) you are trying to create with a particular mix requires more (lighter tone) or less (darker tone) water.
  5. The type of edge effect you are trying to create. A very soft effect where it is not possible to tell when one color finishes and another starts needs more water than an edge which is more definite. The other extreme is where you want hard, definite, edges. In this case you would paint on dry paper – though the mix still has to be wet enough that it will flow.
  6. The size of the shape you are painting. A bigger shape requires more water in your mix so it does not dry between each successive horizontal brush stroke as you paint down your sheet of watercolor paper.
  7. Atmospheric factors need to be taken into account as well. If you are painting in a hot room or environment you will need more water than when painting in a cold one. Outdoors you have to make similar allowances for the wind, which can be really tricky – so much so I rarely try and paint plein air if the wind is too strong.
  8. Finally all of the above are inter-related – this is where the skill comes in!

So next time you get out your watercolor painting gear give yourself some time to look at what the water is doing as you paint. It will certainly improve your results!

Hopefully the above will give you a new insight into watercolor painting which will help you gain more from your art. Watercolor painting is a wonderful medium and I wish you many years of pleasure from it if you are just starting out.

How to Paint Watercolor Paintings

A watercolor painting usually progresses in the following manner:

  • Large shapes to small shapes
  • Wet on wet to wet on dry (could also be read as from soft edges to hard edges)
  • Light tones (more water in a mix) to dark tones (less water in a mix)
  • Cool colors (distance) to warm colours (closer to the viewer)

All four groups move along at a similar pace at about the same time.
