I have f.lux software installed on my computer so that
blue tones are
'turned off' at night on my monitor.
It's been interesting viewing photos of irises with and
without the blue
For example, removing blue tones from the photo of Jazz
Band (iris twiki
photos) shifts the ground color from yellow to orange, has
on the fall band intensity of color, although it does
shift it more
towards red instead of brown.
Is this kind of cyber 'pigment removal' of any use in
presence/absence of actual pigments?
