How to consistently generate the most different colors?

Question

Algorithms

There is such a color generator:

public static function getRandomHexColor()
   {
       return  sprintf('#%02X%02X%02X', rand(20, 200), rand(20, 200), rand(20, 200));
   }

When I call it in a loop, I often end up with very similar colors, for example:


What algorithm can I use to get the most different colors?

Answer 1

The most reliable way is to generate a set of suitable colors in advance and simply choose from a ready-made table, at least in turn, at least randomly with repetition control.
