Hm... I get the blue hue when I set a number of colours to 4 or 5, while accuracy is set to 1 or 2. Still, you are right, the "accuracy" is not even a correct label here. This slider was in fact introduced for performance reasons, as I've been getting colours from images which were >10MB. Higher values on that slider will cause more calculation time, but still, would not certainly guarantee better accuracy. I'll probably rename it and provide the explanation. So thanks!
