Bias towards the color black.

[tunaflsh]

I'm trying to quantize this image. But it is biased towards darker colors, which are less appealing the the brighter colors. And it would make more sense to have more brighter colors in the limited palette. Do you have any idea if I'm setting this incorrectly?

1. Run

rscolorq -i image.png -o image-32-lab.png --op image-32pal-lab.png -n 32 --lab -p --auto -s 0

2. Results

And it's way worse without the --lab color space

Isn't it supposed to generate 32 distinct colors? Instead the color black is repeated multiple times.
