Why would you think that what you perceive as a color match is reliable

a good question, Willi, but simply answered:
You cannot be perceiving color in the same way, but some reliability comes
from the fact that your imitation and the natural are both viewed by human
eyes. Since the actual color spectrum remains constant, a similar
relationship, although viewed through a vastly different nervous system
might remain from the trout's view.

Your point that there's reliability because they are both perceived by
human eyes (which is correct) is irrelevant because (aside from maybe
having more confidence and fishing the fly better) it makes no
difference whether the human thinks the color matches or not. It's the
fish's eye that judges.

Trout perceive a wider spectrum than we do and are able to see colors
than are not visible to us. So even though the color spectrum is
constant, their visible spectrum is different from ours. They are also
able to utilize polarized light which is something else that is alien to
our species. I'm also confident that there are other undiscovered
differences in how they perceive things visually.

How would the trout's optic "wiring" change the way the light is
reflected from an object? As I said in the other post, I can understand
that trout might perceive, for example, what humans call "orange" as
what humans call "purple," but I can't see how trout would arbitrarily
and randomly perceive one color differently. IOW, the trout's
perception of this or that color might be different than a human's, but
it would be consistent. But again, ???
