Colorecall
Memorise two coloured shapes, then rebuild one colour from memory.
Every day: One daily set of four rounds with the same colours for everyone: see two coloured shapes for five seconds, then recreate one shape's colour from memory with hue, saturation and brightness sliders; scores go on a leaderboard. New puzzle: Once a day (the site does not state the time).

Colorecall is a daily colour memory game. In each of four rounds you see two shapes in two colours for five seconds; then one shape returns without its colour and you rebuild it with sliders. The daily uses the same colours for everyone, so scores can be compared on the leaderboard.
About Colorecall
Colorecall tests how well you remember a shade, not just a colour name. Its main mode, Duo, shows two shapes (a donkey and an arrow, say) in two colours for five seconds. Then one shape comes back in grey and you recreate its colour with hue, saturation and brightness sliders. Holding two colours at once is the hard part: they blur together in memory.
The Daily has four rounds and the same colours for every player. Scoring compares your colour with the original in CIELAB, a colour space built to match human vision, so a score reflects how different the colours look rather than how far apart the numbers are. A leaderboard ranks the day's players. Besides Duo there are Classic, Flag and Football Logo modes, and a QuickPlay option for practice.
It is free in the browser with no download or sign-up.
It suits players of colour games such as Hueman or The Daily Hue who want a memory twist.

Tips
- Name the colour to yourself with a detail: not just blue, but dark, greyish blue.
- Pay attention to brightness and saturation as well as hue; memory tends to drift toward typical colours.
- Look at both shapes during the five seconds, since you do not know which will return.
- Set hue first, then brightness, then saturation.
