More on color- misc. rambling observations

Dear All:
The discussion regarding color is fascinating. Comparing the color of a
flower with a color chart should be done in northern and bright light,
not sunlight. When deciding on the merits of a new lily as a cut flower,
we always made sure they looked good under fluorescent light, as such
was that used by florists in their windows and shops. The difference in
the perceived colors under such different light sources can be quite
startling.Cheers, John E. Bryan

The reality is a different reality to each person
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.
