Igor, Paul is correct. In the case of black or similarly dark colors, I
would suggest making a function that identifies how dark your color is
beforehand(such as checking if all 3 RGB values fall beneath a threshold
considering RGB(1,1,1) etc... are still hard to see visually ) and then
increasing the lightness factor accordingly. That should ensure that the
darker colors get lightened more so you can visually tell the difference
easier.
