Color match

I spent last weekend painting color wheels and mixing colors to match fabric. Here’s the result of 8 hours of work last Sunday. Not perfect but I learned a lot and used up all my yellow paint in the process.
Don’t see much yellow, do you? But it’s there. The browns and beiges are based on yellow and violet mixed together with varying amounts of white and red. The green leaf has yellow and red in it. Even the red-violet colors have yellow in them. But nowhere in this painting is there any blue–mainly because I had violet and alizarin crimson paint so I dind’t have to mix those colors myself.
Today we’re painting a monotone. I guess mine will be red, but not orange, chartreuse or dull purple, all of which contain my missing color. I think I’m going to run into trouble when we paint a still life tomorrow and Sunday.
