Also, I've heard that the eyes different responsiveness to various parts of the light spectrum can affect it. For example, two shades of blue in 8 bits that are one bit apart will be completely indistinguishable. But some greens that are one bit apart are discernable. Phenomeneoa like this make 10-bit color sound like a very cool idea to me.
