One of the problems of discussing color is that everyone doesn't have the same color vocabulary. Here's a simple color vocabulary was developed for my students to ensure that everyone will have the same understanding when we talk about color. Once you understand these few words it will be easier to discuss color issues and strategies with fellow artists.
