I figured the rearranged palette would need to have perceptually similar colors close together, so that errors introduced in compression wouldn't change the color much. And the former part worked well: just look at those smooth gradients in the palette. The theory didn't turn out though: that remapped *introduced* a lot of sharp gradients into the image.
