and now I’ve switched over the type of dithering I’m using on the preview image – previously, it was a random dither using «FloydSteinberg» setting and remapped to Netscape’s 216 web-safe color palette – now it’s an 8×8 ordered dither (pattern dither) using 6 colors in each channel (so nominally still the same 216 color palette) – while the pattern dither does give a more retro look, it also allows for smaller file sizes (random dithers have too much randomness to be easily compressed (at least when using lossless compression))
