Although it is possible that one viewer's perception of color may be very different from another's, experimental evidence suggests that the relationships between colors are, in many respects, universal, and thus relatively free from individual and cultural influences. the "experience of color" can be described objectively, so that predictable visual sensations can be elicited by adjusting the relationships among colors. a model of color experience is described that is based on the types of interactions among colors. the model adjusts formal compositional attributes such as hue, value, chroma, and their contrasts, as well as size and proportion. components such as these can be utilized to build a general architecture for adding guidance to interactive systems.
