Backlit · white key

A backlit set: translucent C/M/Y + a translucent white key

Lithophanes are lit from behind, so tone comes from thickness and the key must be a translucent white — a black key would just block the light. For tonal work, the most important spools are a true opaque black and a translucent white that spans dark→light.

On a single nozzle, swap with pause-at-height or M600 at each colour-change layer.
