Gouache paints
come in tubes that the artist uses with a palette.
Gouache (pronounced "gwash") is a type of water-soluble paint that is much like watercolor paint, though it is more opaque. It is diluted with water and applied to heavy paper with a brush in much the same way, but because it is not as translucent as watercolor paint, the artist does not rely on the whiteness of the paper to create light areas in the painting. Gouache paints are available at art supply stores in small tubes.
Instructions
1. Squirt a small amount (about the size of a pencil eraser) of gouache onto a palette. Do this with two or three colors before adding more to the palette. This will give you the opportunity to mix in the open spaces before you add more.
2. Dip your brush into the cup of water and wipe any excess on the edge of the cup. Place the tip of the brush into the paint and then apply it to the paper. Experiment with your mark making. If the paint tends to drag, you might have too much paint on the brush, or you might need more water to thin it. You can redip the brush into the water and thin the paint while it's on the paper.
3. Add more marks to your paper in this way, avoiding areas that are wet. You may go back to those areas after they have dried and layer additional color.
