Paul has it right here too. In researching Glow In The Dark (GID)
materials on my own, other studies have also
shown that Trout tend pick up the Ultraviolet spectrum better too. Why
certain colours work better at lower depths
as opposed to others. I've been experimenting a lot recently with glow
in the dark materials, and
combinations of UV dubbing materials, that all cast of light in
different spectrums as well. Gary Borger
also had something interesting to say on the subject as well.
*Gary Borger
<http://www.finefishing.com/1flyfish/flies/colorovision%20trout.htm> had
this to say on the subject:* /"Night anglers often differ sharply on the
color of the lures they most prefer. Since they all catch fish, they
must all be right. The truth is, when the light level falls below 0.1
foot candle (a typical star-lit night without a moon) all colors become
just shades of gray."

/Someone also mention a good reference book as well, one I was
introduced to first at Fish Tales
in Calgary by David Blair -- but have not yet picked up a copy. I guess
I'll put that on the
list right after I get Paul's book first. ;^)

While I certainly agree that most (if not all) fish can see colour, it's
very important not to generalize from individual experiences as regards
flies. For example, a fly in the surface film on a sunny day will appear
black to the fish, a silhouette, just as it does to you. OTOH, on an
overcast day, all its colours can be distinguished. Time of day, smog,
and a zillion other variables impact on exactly how a "colour" will be
viewed.
Colour of subsurface flies is always seen, but depth (just one variable)
impacts how those colours are seen.
As it happens, I agree with Rene as to the importance of contrast, and a
colour "spot." One can see this in many of my patterns tied with
chartreuse thread to give a "bright" head "spot." This is the theory,
and successful practice, of a myriad of Atlantic salmon flies that have
colourful tags (or butts), and a smaller number that have a bright
collar.

Dave,
there are a lot of experiments done in the past, and at least for trout
and a lot others: yes, they see color.
I've made the same experience. In my home water I fish a lot my 'blue
parachute beetle'. I usually tie it with a red or orange dubbed head. I
tried it several times without the head. ANd these flies catch less
fish. I remember 2 days where the plain blue didn't produce a hit,
switching to the one with the red head produced takes imediately.
Switched back to plain blue - nothing.
I'm sure this is not true for all specied of fish.
