Color is a science, but it’s not difficult to understand. The great thing about the sciences is that, like mathematics, it involves a set of absolute rules and principles that always work in a fixed way that never changes. Once you understand those rules, working with color becomes an intuitive process that doesn’t require much thought, because you already know what to expect as you work with them. In the same way that 2+2 = 4 no matter where you go in the universe, color science is no different. The purpose of this guide is to spell out those rules. Once you know why you’re doing what you’re doing, using Adobe’s color tools will become second nature.
