You'll need to find out how to convert from RGB to HSV

Then all you need to do is look at the hue and fiddle with that.

Sorry I can't be any more help than that, because I don't know what the
maths is to convert from one colour space to the other :(  But this should
be a start

Subject: [PHP] thirds of a color wheel


I'm working on some scripts which generate color schemes from a base color

Working out lighter colors, darker colors and inverse (complimentary) colors
was easy, but now I'm trying to figure out the right math for a triad of
colors (3 colors with equal spacing around the color wheel), given a
starting color.

Any clues would be great :)
