Perceptually uniform interpolation for the spread button on palette dialogue #264
Description
A feature suggestion - often in pixel art the artist will try to create colours in a range that look equal distance apart to the human eye. The traditional rgb linear interpolation of dpaint does a poor job of perceptually uniform steps. Luckily, in the years since the science of interpolating colour spaces has come on a long way.

Since several python libraries already exist to do this, it shouldn’t be too difficult to support:

Maybe a dropdown on the spread button to select “rgb” or “lab” would be a nice UI for this that would fit in with the existing UI
