Hi Bill,
Thanks a lot for all theses links.
When playing with the system color chooser (Mac OS X) I guessed I had
to convert RGB to HSL and back in order to be able to modify the
luminosity value and get a range of colours.
The link below is invaluable :-)
Best Regards from Paris,
Eric Chatonet

I think that as a general approach, you probably want to convert to
HSL,
figure out your colors, then convert back to RGB.
