Random color generation using PHP

Question

I\'m trying to generate random HTML colors in PHP, but I\'m having trouble getting them to look similar, or in the same family. Is there some function I can use to generate

Answer 1

A few years ago I came across this class. It lets you generate complimentary colors based on a seed value.

If you're looking for something more general, limit yourself to a general range using rand (obviously below 255) and the use base_convert.
