RSPCOLOR (register)
When:
X = 1
RSPCOLOR returns the sprite multicolor 1
X = 2
RSPCOLOR returns the sprite multicolor 2
The returned color value is a value between 1 and 16. The

20 SPRCOLOR 5,7
30 PRINT"SPRITE MULTICOLOR 1 IS";RSPCOLOR(1)
40 PRINT"SPRITE MULTICOLOR 2 IS";RSPCOLOR(2)

Line 20 selects sprite multicolors 1 and 2. Lines 30 and 40 print
the RSPCOLOR values for multicolor 1 and 2.
