Re^2: Ordering colors for contrast (luma)

I sorted them using your luma function and got this which doesn't have the effect I'm looking for. It seems to concentrate similar colors together. Eg. the yellows and light silver at the far end, the blues and greens at the near end, the reds and pinks in a couple of bunches.

I'm slowly working my way the the links you posted, but they seem to be mostly about picking one color to contrast with one other color; and I'm stuck to think of a way to use that order 64 colors for my purpose.

I approaching the conclusion that it might be an NP problem: basically, like trying to arrange the numbers 1 through 64 such that you maximise the sum of the differences between adjacent numbers.

Taking note of the interleaving done in your fudgy examples, and looking at the results, I wondered what the result would look like if I did the Luma sort followed by a full interleave (rather than your 4 partial interleaves) and I was very pleasantly surprised by the result. Whilst the color-blind compatible stuff is good for small sets (<=12), I've a need for a greater range and I think this luma-sorted & interleaved is pretty good for up to 64 colors on black or white backgrounds.
