Are you looking for some colors to use on your charts and graphs? Are you looking for some colors that are “easy” on the eyes? I don’t want to use the standard colors on my charts because they tend to look too intense, almost child-like. You also want to choose colors that work well together. And thirdly, you want to take into consideration those that are color blind, or have difficulty distinguishing certain colors.
