Increase color's saturation

[TaleOfTimes]

This is a lot harder than i thought.

All i want is to increase a pictures saturation by an input amount.
So i figure i most go color by color and increase saturation.

I have tried converting RGB to HSL (or HLS?) and i just cant get the conversions to work rite, ive looked at several on the internet and i cant find something working.

any help would be appriciated

This (vb.net) will get a color from h,s,b values:

And there already is color.gethue, .getbrightness, getsaturation.
