The clever part here is that it looks almost like C64 multicolour, but without the usual 2×1 pixel trade-off. Instead, the image keeps a crisp 1×1 pixel aspect ratio.

The first ingredient is a hi-res charset layer, which carries the fine pixel detail:

Beneath that sits a layer of multicolour sprites, contributing the extra colour range.

With careful dithering between both layers, the final image appears much richer and smoother than such a simple setup would suggest.
