From what I can tell, IT IS NOT limited to paired hexes - See http://www.december.com/html/spec/color3hex1.html - this pages lists 512 colors, the next another 1024 colors, the next another 1024, and the last yet another 1024 for a total of 3584 colors
That is more than the paired sets I believe but math isn't my specialty. <<snip>>
It seems to me that the first page, like the others, shows 1024 colors rather than 512. This makes an overall total of 4096. In each triplet, there are 16 possibilities for each of three positions, yielding
16*16*16 = 4096 individual colors. So it checks out that way.
The full six hex digit representation for a color yields
16*16*16*16*16*16 = 16777216 individual colors.
It would hardly be possible to represent 16,777,216 colors with only 4,096 possibilities. I say "hardly" so some programmer type won't start saying, "hash functions".
