The most noticeable aspect of color is its value. If you can organize your colors, especially as your art is developing, as either clearly dark or clearly light values, you will be better able to see the design of your art emerging. Try to have your colors “group” together into light or dark colors. An easy way to see if this is working, is to view your art from a distance. It is super helpful if you can clearly see what is light and what is dark. Not only does this make your art stronger, but it also makes your art more clear, so you can choose what to do next.
