Consider the following color pairs and their distances:

cf5440 -- #c69141: 39.6

72893f -- #7b7eca: 85.4

The first pair appears (to me at least, and I think I have pretty normal vision) more different than the second pair, and yet the second pair has a much greater distance. What difference metric is used? Is it something like one of these algorithms, or is it something simpler?
