Chroma is a daily colour mixing puzzle. You pick colours and set their proportions in 5 percent steps, and each try shows how close your mix lands to the hidden target colour. Get within 95 percent within six tries to solve it; a Hard mode adds a fourth colour.

About Chroma

Chroma gives you a target colour and a set of shades to mix. You choose colours and adjust their proportions with plus and minus buttons in 5 percent steps until the weights add up to 100, then submit. Each row of your history shows a percentage: how close your mix landed to the target, with 100 a perfect match.

There is no single right recipe, and the order of colours does not matter: any mix within 95 percent of the target counts as a solve, and you have six tries. Hard mode, switched on with the gear icon, gives you four colours to balance instead of three for the same target, and both modes count toward one streak.

Chroma is one of the daily games on Greatest Games, a site of word and logic puzzles. A new puzzle goes up every day at midnight US Eastern, the same for everyone, and it plays free in the browser with no account or download. The Chroma archive lists every past puzzle by date: a free account plays the last seven days, and the paid Greatest Games Plus plays them all and removes the ads.

The mixer works like light rather than paint: it averages the colours you choose, so blue and yellow drift toward grey instead of making green. Getting the lightness right matters as much as the hue, which makes the game a small lesson in how screens build colour.

Tips

Get the main colour family right first, then fine-tune the smaller amounts.
Change one proportion at a time so you can see what each step does.
A mix that is too dark or too light usually needs a shift in the lightest or darkest shade.
Try Hard mode once Easy feels routine.
Yellow and blue average toward grey here, not green: for a green target, put a green or a close neighbour in the mix.
