Alex,
In that all the light in the world comes from above the water's surface, I would think that the number of wraps of hackle, and the stiffness of the hackles would have more to do with the accurate footprint of the fly than the color. When a fish looks up at the viscous layer (surface tension) of water and sees a fly, it is really looking at the footprint the fly makes in the surface tension. So, with the light coming from above, color would have less to do with triggering a strike than appearance.
I can't believe I just gave Alex Argyros advise on tying flies. HOLY MACKEREL!
