About
Off Colors is a set of short perception games. Each one shows you something for a few seconds, takes it away, and asks you to rebuild it from memory. You get a score out of ten per round and fifty for a run.
The games
Difficulty
- Easy — Five seconds to look. Generous scoring.
- Hard — Three seconds to look. Near misses cost you.
- Brutal — A second and a half. Only precision scores.
How scoring works
Every round produces a normalised error between 0 (exact) and 1 (as wrong as the dial allows). That error is raised to a falloff exponent that gets steeper with difficulty, so a near miss is worth a lot on Easy and very little on Brutal.
In the colour games, hue is weighted by the target's saturation: missing the hue of a near-grey barely costs you, because a near-grey hardly has one.
