To reduce the amount of colors of non-pixelart images, we currently pick the n most common colors and replace all other colors with the closest selected color. There are three big areas for optimization:

• Proposing a target color set (e.g. with k-means?)
• Improve the distance function, which currently only calculates the sum of differences of RGB values.
• Reducing the palette of an image to the target color set

Downscaling currently samples pixels, preserving original colors but destroying edges and reducing details. Likely, there are better algorithms to preserve pixelated edges or pixelate regular images, e.g. https://en.wikipedia.org/wiki/Seam_carving?
