To quote the great philosopher Don Hertzfeldt, "I...am a banana!" I love the color yellow, primarily because it seems to cheer me up, speaking as it does of things I like: Spring, Fall, and tropical fruit. Yellow is also a pain in the butt to shade, since you really have to keep a close eye on the color temperature of the shading as you go. Too warm, and it looks "glowy", too cool and it gets sort of dead and moldy looking. In these pieces recently, I've been using up a tube of Hansa Yellow Light as my base yellow color. It's not my favorite yellow, since its tinting strength is relatively weak, but it sure makes you think when painting, which is always a good thing when doing exercises like this.
