Hmmm... I dunno. I was thinking in terms of staying with the rainbow colors, so let's see. Of the ones that are left, I tend to like Indigo for Chris - it's a good, deep, mourning sort of color. (*iz biased, because my Chris icon was indigo-ish* ;) )

For the others, I think I'd end up with Orange/Josiah, Yellow/Nathan, and Violet/JD... but I can't explain why. Just gut-instinct on what I like best.
