A git format patch to solve the bug. To apply use:

  git am 0001-Fix-bug-692235.patch

This changes the RGBK space to be a 6x6x6 RGB cube, supplemented by 40
greyscales.

The results are significantly better than the existing version.

Unless anyone objects, I'll commit this fairly soon, so please test and speak
up!
