Color is not a property of an object, but a perception. Four factors — light source, object, observer and context — together determine what we see. Understand these components and take control of your color assessments.
The human visual system is not a calibrated measuring device. Cone variation, color blindness and age effects mean that no two assessors perceive identically. Understand the biology behind color assessment.
Visual color assessment depends entirely on the observer. Learn everything about color vision testing, individual variations, training requirements, and environmental factors for reliable visual evaluation.
