In the CExtBitmap class there are two static methods, stat_RGBtoHSL and stat_HLStoRGB, that should help you perform these conversions.

What you need is an RGB to HSL conversion algorithm. You can find a lot of implementation if it on the net, this is the first I’ve found: Paul Bourke’s Converting between various colour spaces. The code given on that page is in C, so probably it won’t give you any trouble using it.
