Also, I know there's red/green colorblindness and blue/green colorblindness ... any other color combos to avoid?

Sorry I can't help with the rest, but there's blue-yellow (much less common than red-green, which makes up about 99% of colorblindness but more common than blue-green, as far as I remember).

And maybe this: http://www.etre.com/tools/colourblindsimulator/ can help with that part.
