wakeNbake,

You will need to look at the value of each of the 3 individual RGB elements and do some calculations to get a mean value - the higher the value the "lighter" the overall colour. ;)

In technical terms you need to translate the RGB values into HSL (Hue, Saturation, Luminance) to get a valid result. There are several websites that give various formulae to do this - this one seems pretty good - but a really simple calculation that I have found pretty reliable is:

Luminance = (Red_Value * 0.3) + (Green_Value * 0.59) + (Blue_Value * 0.11)

So all you need to do is to plug in the return values from _ColorGetRed, _ColorGetGreen and _ColorGetBlue into that formula and you have your Luminance result on a scale of 0 to 255.

I hope this helps. :huh2:
