What type of colorization are you interested in? For example, you
could use Quartz 2D and ColorSync to convert the image to Grayscale.
Then you could overlay that grayscale image with a transparent red
filter. The overall effect would be a reddish-tone image.
Beyond that, you could always draw the image into an offscreen buffer
and apply whatever colorization operations you care to a the pixel
level.
Using Core Image in Tiger would also be a good tool for applying color
effects to an image (if you can ensure that you have Tiger).
It all kinda depends on what kind of colorization you want to use.
