The issue of presentation already answered. As for arithmetical ways that
depends on the color model assuming that pixel represents a color space
point. There are various models L*a*b, RGB, HLS, HSV, IHLS. Mathematical
operations over color space points, e.g. "darken", "+", "average," are
implemented within these models slightly or very differently.
P.S. Ada has bindings to major graphical frameworks (Qt, GTK, Win32 GDI).
