Okolors
Okolors generates high quality color palettes from an image for your theming needs. It does this by converting the image's pixels to the Oklab color space and then performing k-means clustering. By using a proper color space for color difference and a more accurate clustering algorithm, this helps to ensure that the generated palette is truly representative of the input image.
If you are looking for the CLI application, see the Github page.
