Pixel art is likely to have only a few dominant colors, so it should convert losslessly or nearly so. Most other quantization implementations unconditionally drop a few least significant bits of colors, giving images a posterized look of a 16-bit console. pngquant tries very hard not to do that, as its goal is to have no visible loss, just smaller files.
