I don't think floats will help our cause at all. This would just use more space
(at least I haven't seen a usable 8bit floating point specification yet) and we
would probably use less of the values range. In floating point representation
when dealing with colors only [0.0, 1.0] is used.

8bit per component are sufficient for the human eye. This leads to 2 ^ (3*8) =
16.777.216 colors. Can you differentiate any pair of them I would show you?
