Why does oil pastel resist watercolor?
The reason it’s called resist art is because oil and water are not compatible so the oil pastels resist the watercolours. What this means is the watercolours won’t be absorbed into the paper when they come in contact with the pastels. Oil pastels are made from pigments mixed with oil and a wax binder, making them water resistant. If you paint over top of oil pastels they will resist the paint and will never really dry out completely. Remember grade school art class and painting with watercolor over crayon drawings? It’s like that. Oil pastels can be used on all sorts of supports from metal to wood to paper and in all sorts of mixed media work. It is worth noting that they repel water so can be used as a ‘wax resist’ type technique to great effect with watercolour painting. – Oil pastels can be used in a lot of different ways. Ask how many students have used oil pastels before, and how they have used them. Explain that because oil and water don’t mix, when you paint over oil pastel the marks will still be visible – this technique is called oil pastel resist. Since light is a major catalyst, watercolors should be kept out of direct light and protected by a sheet of filtered glass or acrylic. They should also be mounted in acid-free mat board to keep the paper from discoloring over time. Pastels will never completely dissolve or turn into paint but they are really fun to use because you can hold onto those marks, scribbles and strokes. The colors may change or look different once you add water so I recommend experimenting with those pastels before diving into your project.
Which is better oil pastel or watercolor?
Oil Paints come across as more 3-Dimensional Because of the transparency of the layers, it’s easier to create depth in oil paints through glazing and underpainting for shadows and highlights. This makes it easier to achieve more hyperrealistic effects with oils rather than watercolours. The disadvantages of watercolour include paint pigments that dry lighter than when they’re first applied, watercolours can only be painted on thick water absorbent paper, and the wrong paint to water ratio can ruin your painting. Oil pastels can be used on all sorts of supports from metal to wood to paper and in all sorts of mixed media work. It is worth noting that they repel water so can be used as a ‘wax resist’ type technique to great effect with watercolour painting. Watercolour is the hardest medium to master because it can be very difficult to fix mistakes. The transparent nature of watercolour means that mistakes show through the layers. As such, you cannot easily erase or paint over the errors in the same way that you would with opaque mediums such as acrylic or oil.
Is oil pastel good on watercolor paper?
Rough watercolor paper: Watercolor paper can be used with pastels because of its toothed texture. This will provide a gentler surface ideal for blending with your finger. Bristol and illustration board: Cold-pressed Bristol and illustration boards are perfect to use with oil pastels. You can use a cloth to blend pastels, but chamois are even more effective. Chamois is a type of super-soft and flexible leather that is excellent for blending colors with pastels. For large areas, you can wipe or rub the chamois across the surface of your paper. Oil pastels can be manipulated with solvents such as mineral spirits and Turpenoid. They can also be mixed with linseed oil and other oil paint- ing mediums. The first step is to seal or fix your painting with an aerosol fixative or an aerosol varnish to provide a waterproof protective layer. This first layer will seal and adhere the pigments deeper into the paper. Using a brush with a water-soluble liquid varnish would re-activate the pigment and ruin your artwork. No expensive supplies are needed! I used oil pastels but wax crayons would work too. My favourite texture is made with the stub of a wax candle and some paint. I use gouache, because that’s what I have, but any paint will work.
Can you put oil pastel on top of watercolor?
You start out by drawing with oil pastels on watercolor paper. Then paint over your drawings. The oily oil pastels resist the watery liquid watercolor paint (oil and water don’t mix, remember?) so while the paint soaks into the paper, it just beads off the oil pastel lines, swirls, and scribbles. It seemed a natural step to add vibrant pigment to watercolor by applying pastels over dry watercolor. Especially if you prefer a loose style of painting. Sketches and impressions are ideal for this approach. Beautiful on its own, soft pastels also look great when combined with other media. An oil pastel is a painting and drawing medium formed into a stick which consists of pigment mixed with a binder mixture of non-drying oil and wax, in contrast to other pastel sticks which are made with a gum or methyl cellulose binder, and in contrast to wax crayons which are made without oil.

You may also use lighter colors to blend over darker colors. Watercolor paper is also a suitable surface for pastels because it’s strong and can be purchased in a range of textures. On a beginner level, use oil pastels to simply draw and blend with your fingers. Use a spatula or palette knife to blend while adding texture to your artwork.

In commercially made watercolor paints, the binder is either natural gum arabic or synthetic glycol. This is what holds the pigment in suspension.
