The third technique is the least predictable, but produces a very realistic result. We are going to work wet on wet, laying down the blue water first and then dropping in the windmill.
Have your paper lying flat for this technique. Lay down a wash of cerulean blue over the whole water area, and then wait for a little until this begins to dry. If you go in too soon with other colours they will spread too far and fade to nothing, and if you go in too late the paint may cause cauliflowers and backruns to form, or just not blend at all.
