components of color assessment

“in visual perception a color is almost never seen as it really is- as it physically is. in order to use color effectively it is necessary to recognize that color deceives continually” ( albers, 1975 )

“the sources of deception can be categorized into the effects of the source of light, the object itself and the observer of the sensation of color, each of which must be properly controlled in order to ensure effective and repeatable visual assessment of color.”
