I tried comparing the hex values directly, but there were inaccuracies, maybe the same ones you've been having. I think since the value of a particular color precedes with a 0 even when it's below 17(0F), the preceding 0 causes a shifting in the comparison. It would, for example, cause 0x000000 to seem farther to 0x123456 than 0x00FF00, where visually you can see clearly that black is closer to 0x000000.
btw in my example, var a = 0x12345 where it should be 0x123456. The numbers hold to be accurate after correcting this typo.
