So frustrating!

Red~& = _RGB32(255, 0, 0)
Green~& = _RGB32(0, 255, 0) ' very light green almost yellow
Blue~&  = _RGB32(0, 0, 255)
Yellow~& = _RGB32(255, 255, 0)
Purple~& = _RGB32(255, 0, 255)
Cyan~& = _RGB32(0, 255, 255)
Black~& = _RGB32(0, 0, 0)
White~& = _RGB32(255, 255, 255)

see _RGB32 in Wiki for complete description.

So red print on blue paper:
Color _RGB32(255, 0, 0), _RGB32(0, 0, 255)

Where you see 255 you can replace with number 0 to 255 for different shades.
