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.
