Hue

Hue is built on a single mechanic with unusually deep implications. You rotate a color wheel that changes the background color of the entire world, and any object the same color as the background disappears. Pink platforms vanish when the sky turns pink; yellow walls open when you shift the world yellow.

Fiddlesticks Games layered the mechanic into a story about Anne, a colorblindness researcher who has disappeared, and Hue, her son, picking up fragments of her work and learning to perceive color for the first time. The narration — voiced by Anna Acton and Matthew Wade — is heartfelt rather than puzzle-padding, threading themes of loss and remorse through the otherwise abstract environments.

The art is strict silhouette against bright single-color backdrops, with over 30 original tracks composed for the game. Full colorblind support uses symbols as a secondary cue alongside hue, so the central mechanic works for players who can't distinguish the colors themselves. The puzzles ramp from individual obstacles to whole rooms whose layout exists only when you can see — or remove — the right hue.
