What does a pigeon look like?

I got curious about this after reading a blog article on pigeons and face recognition. What colors does a pigeon see in other pigeons? I see pigeons with white, black, and grey bands and patches, sometimes with iridescence in the neck. The wikipedia entry for bird vision says they have pentachromatic vision. [more inside]

How can I color correct my digital photos if I don't see colors well?

I want to color correct my digital photos, but I have a color vision deficiency. Up to now, I've been correcting the levels manually, but relying on the auto-color features in Picasa or Photoshop for colors, but often this doesn't do a good job and the colors look off, even to me. I can manually correct the levels and adjust the colors so they look right to me, but that doesn't guarantee they will look right to others. Is there any way to color correct numerically (for instance, using the eyedropper tool on someone's face to to see if the RGB value of skin falls within a skin-tone range) Otherwise, is there a service that I can send my digital photos to where they can color correct them perfectly and send them back? I'm interested in the digital files, not in getting prints.

why do colors seem to appear in different planes on my LCD screen?

When I look at an image (on my LCD computer screen) that is composed of a combination of solid colors separated by black borders, I perceive the colors as appearing on different planes of depth, as if the image were three-dimensional. If I close either eye, the illusion collapses. Am I the only one affected by this, or is it a consequence of the way LCDs display color? [more inside]
