Pigmentone

Pigmentone is a color-guessing game in which you move emitters and combine or divide colors across multiple rainbow rings. You use trial and error to give every receiver its target color and complete each level.

How the puzzles work

Emitters produce beams of their own color and can move only along the edge of the screen. Receivers take on the color of an emitter’s beam. Each receiver has a surrounding rainbow ring that matches its center circle when it has the correct color. Receivers can be combined in different colors, and can send beams to pass their color to other receivers.

Obstacles are white rectangles that block beams. Prisms split a combined color, but only when it comes directly from the receiver where the colors were combined. Two triangles on each prism indicate the directions in which it sends the rays. Invisible pipelines divert beams along preset routes and become visible when a ray touches them.

Levels and features

The game has 50 levels, a real-time color-combination system based on colored light rather than the rules of material colors, and simple graphics. It also includes relaxing music, a help system that punishes you for using it, and time-trial scoring for replaying puzzles.
