Awhile ago the question of color of flies came up in ROFF. Some people
(including me) thought that fish would likely see colors very
differently from people. Others (rdean, for example) thought that there
would be a one-to-one relationship between the colors fish see and the
colors fish (we?) see, so it wouldn't matter.


Most mammals have only two types of cones

what about Cone Heads?

..........basically I agree. Color is an interesting subject.
Perhaps they see it differently, but if rdean is right,
it doesn't matter. Either way
there is no way to know, except by hunch and by
trial and error. Raptors can see ultra violet reflected by gopher
urine.
So our perception of gopher **** is not one to one with
raptors.

I just thought it was interesting. Pmds do indeed look
very yellow from a distance. And they look gray-olive
up close. Does it matter to the fly tyer?

**** I dunno.
