roygbp = 6*3 + b + gr + w = 21 smileys. That's 3 shades of Red, orange, yellow, green, blue, and purple each, plus black, grey, and white. Should be enough for some smileyart, methinks. And most certainly not unfathomable. Maybe even add some brown in there. Have some smileys reppin' the C-sikky-fo', too.
