    Hi, if i have an RGB color how do i make it lighter and darker? I need to emboss things like borders and button edges on to a textured background.
    Also it needs to be fairly fast so a reasonable aproximation would be ok. I did think i could just add a fixed amount to each channel but im not sure if that would look right.
