A Fixture
I think a a few picks of this might be worth showing Ron. A pic is better than a thousand wordsRon T, with this method whites are much more fun. I use a 'scrub' coat of a suitable shadow colour and thin it back. Then I brush in mids and thin back. For the highs I add a hint of the colour that is next to the white, (in the surrounding area) and draw that across the tops of the folds etc. In this way you can do a lot of the work very quickly and, once dry, you can work in any other colours for effect by going over the top of the others and again thinning back till it becomes transparent again.
It is all about allowing the underlying colours to come through, which does the blending for you. Yellow and red are handled in the same way.
