Can export any given color.Palette to a GIMP.

The generated palette is not 100% optimal, but it's usable.

The palette is generated by first grouping colors into N intensity levels and then use the median color of each group.

Can generate palettes of N colors relatively quickly.

The above palettes are sorted with this method. Palettes can be sorted by hue, luminance and chroma, using the HCL colorspace and the go-colorful package, with the included palgen.Sort function. The palette can be extracted and saved as a PNG image, using png2png, or as a GIMP palette, using png2gpl. It works fine, and is relatively fast, but there even better algorithms out there if you are looking for the optimal palette and want to adjust for which colors the human eye are most sensitive for.

As far as I know, no other software uses this algorithm. The generated palette may be shorter than N if there are not enough colors in the given image. When the number of colors in a group is even, the average of the two center colors are used as the median, but the two center colors are saved for later and added to the generated palette if there are duplicate colors. For each group, the median value is used. The palettes are generated by first dividing the colors in the image into N groups, sorted by intensity. Given an image, create a palette of N colors, or convert True Color images to indexed ones.
