The perception of a "color" is an event charactized by a blend of three
components:

The light source (illuminant)
The interaction of an object with the illuminant
The observer

The response of the observer is non-linear and cannot be explained simply by
trichromacy (red, green, blue receptors)

As the cornea ages and yellows, response to color (mostly blue and green)
changes

The human eye is deficient in discrimination of yellows

Humans are more sensitive to discrepancies in hue than discrepancies in
saturation or brightness

Memory colors (i.e. skin tone, green grass, sky blue) matter more than
non-memory colors.

Relationships between colors are more important than the colors themselves.

The surface of an object and the manner in which it reflects, transmits or
fluoresces light is important to the perception of color.
