Color theory is the study of how colors relate to and affect each other — which combinations feel harmonious, which create tension, and which pairings are functionally impossible for some portion of any audience to distinguish. In interface design, color rarely works alone; its meaning comes from relationships, a color relative to what's next to it, more than from any single hue in isolation.
