I don't see any trace of yellow, even palest
yellow, in those standards, but gray tones in iris usually indicate both oil
soluble and water soluble pigments are present, but in fairly low dosage.
The co-pigments that make blue-violet anthocyanins look their bluest don't mix
well with pale cream--they look gray.
The yellow or cream that is Tttt for the
lycopene-conversion factor (pink) tends to be a warmer, brighter cream or yellow
than those with lower dosages of the recessive "t." Some yellow pigments
have a faintly greenish tone--a dull, grayed green at best, but when the
conversion factor is present three times the color warms and the two pigments
mix visually to some delightful tones. I suspect the unique
magenta color of PATIENCE is the result of a warm cream and a warm violet
present in the same flower. There's no gray tone to the
