When does the daily Chroma reset?

A new puzzle rolls over at 8:00 PM America/New_York (Eastern), tracking EST/EDT automatically. Everyone worldwide plays the same puzzle for a given day index.

Why are the sliders stepped?

Sixteen levels per channel (steps of 17) keep the search space at 4,096 colors — large enough to be interesting, small enough that directional feedback lets a competent player finish in about four guesses. Snappy clicks beat pixel-perfect dragging.

Why don't the swatches touch?

The human eye is excellent at detecting a seam. Separating Target and Your mix by at least 48px of page background preserves the perception challenge instead of turning it into edge-matching.

Is the answer stored on a server?

No. The color is generated deterministically from the date in your browser. Progress and streaks live in localStorage on your device.

Does practice mode affect my streak?

No. Practice uses a random seed and never updates daily stats or streaks. Share is disabled in practice because there is no shared day number.

Why are some colors never the answer?

Near-black, near-white, near-grey, and low-saturation colors are filtered out so the puzzle stays fair to judge by eye. Valid answers keep HSL lightness between 25%–80% and saturation at least 30%, and the three channels aren't all within one level of each other.
