Why can't you do with the stock transparency routines ?
Or are you concerned about speed (one compare per pixel
(or a call if you weren't already using trans routines)) ?
Granted, it's a bit slow with non indexed modes if you
want to test several colors, as making it table driven
would require quite huge tables. I do that in my game
(a grayscale image is tinted to the "right" color) and
it works a treat. But then it's not done many times per
frame.
On a side note, maybe fblend would help there, since it
has a function call per scanline instead of per pixel.
Look it up on ... sourceforge IIRC ..
