Color2

A speed round on the colours you think you already know. A recognisable character appears with a key element stripped to the wrong shade, Mario in a green cap, and a counter marked Seconds to answer starts falling while you drag the hue, saturation and brightness strips to put it right. Five figures per run. The subject pool covers cartoons, pop-culture icons and logos.

1. Choose a difficulty. It sets how many seconds you get, and Brutal leaves you a shade over three.
2. Start a solo run. The character appears already tinted wrong, with the sliders live down the left edge.
3. Drag hue first, then saturation and brightness, watching the character repaint as you go. Lock in before the counter hits zero.

Testing colour memory on abstract swatches is fair but forgettable. Testing it on Mario's cap is neither, because you have seen that red ten thousand times and you still cannot place it. The side-by-side portraits at the end of each round are what makes the miss impossible to argue with, and the three-second-ish clock on Brutal turns the whole thing into reflex rather than deliberation. Free, no account, five rounds, and a daily set shared with everyone.

Two round portraits of the same character, yours and the correct one, next to each other. That side-by-side is what makes it land: an abstract swatch two shades off looks fine, but a Mario in the wrong red looks obviously, embarrassingly wrong. The score runs to two decimals and the game adds a one-line verdict. A 1.01 earns the observation that your short-term memory has a very short term.

Solo

Five characters at your chosen difficulty, as many runs as you want.

Daily

Five pop-culture icons, the same set for everyone, one attempt. The screen shows how long is left on the current day.

Multiplayer, live

Host a round and everyone plays it at once.

Multiplayer, challenge link

Share a link and each player takes the same five whenever they like. The setup screen also lets you pick the content, for instance cartoons and logos together.

• Commit to a hue in the first second. The clock is short enough that a run of small corrective nudges will time out before it converges, and a decisive wrong-ish hue outscores an indecisive right one.
• Cartoon palettes are near-maximum saturation. If your instinct is to soften the colour to make it look natural, that instinct is costing you points here.
• Read the whole character, not the recoloured patch. Mario's blue dungarees are still correct on screen and they tell you the intended saturation level of the missing red.
