Dry Fly Wings

I read on the web recently that the color of dry fly wings doesn't really
matter all that much. The article stated that the 'footprint' of the fly
matters to the fish, the wing matters to the fisherman. This makes sense to
me. When I hold up a fly to see its profile I see shape not color. When a
fish sees a fly backlit from the sky it can't see too much color.

Which brings me to the question...does anyone here disregard dry fly
pattern's wing materials and just use a visible white or bold color for
better visibility?

I've been making deer hair types of flies lately, and the bleached hair is
sooo much easier to see than natural or dyed hair.

In fact, I find myself leaning more and more to the idea of flies being
either light colored, dark colored, or in-between grey.

Any thoughts? Suggestions? Flames?
