I need to create in C# a matrix of 16 X 16 clickable rectangles, then filling each rectangle with a color from a 256 colors palette (GIF).
I just need help to create a simple class to generate 256 colors.
Couple nested loops might actually cause a bunch of clashing. You want maximally distinct colors. Here's like 1022 I generated. Took like a month to run them through CIE-LAB de2000.
The first 256 will look like:
These even start to clash. 256 moderately different colors is hard to do even with brute force and the best color distance algorithms on the planet.
Static lists are the way to go here. But, things will still clash with that many colors.
public static final String[] indexcolors = new String[]{
