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.

In the experiment, the two humans changed lab coats. The article does not show a picture of the coats, but I've been wondering if they were solid colors or patterned. If the humans wore lab coats that resembled patterns in the plumage of a pigeon, maybe they'd be harder to recognize when they swapped the coats. Do pigeons pay attention to uniform expanses of color?
What advantages do they get from pentachromatic vision? How does a pentachromatic eye perceive colors in a scene? And, this also had me wondering, why don't pigeons have more variations in the color of their feathers? Or maybe they do, but not in my frequency range?
