how to make sthg glow in red!

Good Morning...
i have a series of bitmaps (40 of them) that represent the frames of a monster moving.
they are all put in one giant bitmap under each other (if one frame is 100*100, the giant one is 100*4000)

now, i want the monster to glow in red (on and off). so the first frame should have a little red added, the second one, more red added, and so on, till we reach the middle one, and then red keeps on lowering... (i hope you got the idea).

now, how can i do it? *how can i give the monster shades of red without affecting the black matte around him? *how can i give each frame a different shade?

thank you very much in advacne...
