Long ago way back in college, I came across the artwork of the artist Robert Delaunay (1884-1941). He was a French cubist painter and I love the way he handles paint. It's not just his wonderful colors or his use of color but also how he makes the paint work. Within his abstract, colorful abstractions he models the paint, shading with color which gives his work depth and character.
