The ncard has a great skinning communnity, but the skin sites are mostly in japanese. Ncard is a lot easier to skin too. No screwing with what color FF0011 translates to. The ncard allows you to say how much of each color you want. (1-32) Ie 31 red 1 green 1 blue produces red text. Its easier to find the good skins when their are fewer(NCard) that it is to wade through childish crap(R4) to find a suitable skin.
What is so hard about using hex codes for colors? Most people who don't want to experiment with getting colors right will use a tool to select a color and get the values that way which would work for skinning either.
