color-lightness-merge — Traditional AI Model
Colorizing an old photo with a generative model tends to redraw it — faces drift, grain and fine detail change. This keeps the original's lightness, every shadow, highlight and detail, and takes only hue and saturation from the colorized version, so the result is the original photo in color. CPU, a few seconds.
