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 HTH Martin -----Original Message----- From: Justin French [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 31, 2002 2:56 PM To: php Subject: [PHP] thirds of a color wheel Hi, I'm working on some scripts which generate color schemes from a base color (RRRGGGBBB). 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 :) Justin French -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
