Seems to me you could add 10% to each of the RGB values by multiplying each by 1.1, then round them up. (A roundUp function can be made by div'ing a value by itself, then adding the mod of a value by itself and conditionally adding 1 if the mod is not 0). That would give you the shade lighter. Dividing the values by 1.1 would give you a shade darker. But that is just me conjecturing off the top of my head.
