Color doesn’t exist out there. Color is produced inside us. Color is the human response to vibrations in a narrow part of the electromagnetic spectrum.
Color is an event. In any color event you need a light source and an observer – and often an object that reflects the light perceived. There is no color without an observer – just energetic vibrations.
Our perception of color is complex; part physical, part biological, part psychological. Understanding more about our different responses to color and how they interact helps visual artists be more visually sensitive observers and more effective communicators.
