When enabled, all sprites separated by fully transparent pixels are detected automatically. Select a sprite or use the full image (default).

Color distance cutoff (0 = off, 100 = aggressive merge)

After noise removal, quantize down to a target palette size. All algorithms operate on the post-noise color set (typically <100 colors), so speed differences are negligible — choose by quality preference.

Independent of palette consolidation — remaps every pixel to its nearest palette color using perceptual distance instead of RGB. Fixes color assignment distortions that RGB nearest-neighbor introduces, especially in blues and purples.

Each pixel block is reduced to its dominant color (mode sampling)
