You can get a palette from Opencv using kmeans clustering

I think this one don’t builds a palette by default, just one dominant color. but could help in some way maybe

cool @bidul, this fork has this really nice example:

I made another fork based on the stc one.

stc example-weights can sort colors weighted based on their areas, their order is based on their chroma values.
my example-weights2 can sort by Hue, Saturation, Brightness or the above one.
It has a gui too to change the number of colors, the sorting type, etc on the fly.
There’s some image loading from url too.
