In watercoloring, it is essential to know how to lighten colors, brighten overloaded areas, alternate textures and, especially, correct mistakes.
- This procedure is easier to do on wet paint than on dry paint.
- You need to work with clean tools, to keep from muddying the colors.
With a paintbrush
Moisten a medium paintbrush then apply to the part of the wash you want to lighten. Remove the excess color with a blotter. Repeat the operation until you have the shade you want.
With a cotton swab
Lightly rub the surface being treated with a dry cotton swab. Be careful, it is very absorbent and should only be applied briefly.
With a sponge
Moisten your sponge with water, wring it out, then apply it to the part being lightened. Press the sponge down on the paper to make it absorb the pigments better.
Use a sponge on very large areas, such as a sky.
With a blotter
A blotter, while less flexible than a paper towel, is nevertheless very absorbent. There are two possible techniques:
Use coarse sandpaper to gently sand the area being lightened: little bursts of light will appear on the sanded surface. For rough grain paper, sand harder.
Note: only use this technique on high grammage paper!
