Adjacent Possible

Quickly explore the full search space of possible colour combinations, impossible you say, well perhaps, but using a simple genetic algorithm you can navigate through the red * green * blue colour permutations without traversing through the full cohort of 255* 255 * 255 unique colours.

Click on two colour tiles to instruct the algorithm to generate some similar, but not quite identical, colours, with some randomness added to the ensure a few extra options for consideration in the next iteration.

With this technique you will find yourself a few clicks away from any particular region of colour you wish consider or simply explore to 'discover' colours you may not have considered.
