Well to get back to Component Colors, it's

alpha = (argb shr 24) and 255
red = (argb shr 16) and 255
green = (argb shr 8) and 255
blue = (argb and 255)

Then to get them back to an int

argb = (alpha shl 24) or (red shl 16) or (green shl 8) or (blue)

So I guess you would grab the green, blue and alpha, and make a new argb int with those and your new red value.

EDIT: And, of course, if it's BlitzMax, it's & and | rather than "And" and "Or" but I'm sure you already knew that.
