A small, free place to make color sequences.

Color Sequence Lab is a nonprofit project made so anyone can create and follow color sequences for lighthearted fun, creative exercises, and simple group activities.

The website is free to use. It does not run gambling, accept bets, sell chances, or offer cash or physical prizes. A generated sequence is only a saved color result; it is not a prediction, a promise of winning, or a financial product.

How it works

The server creates each sequence, saves its public result, and gives it a unique ID. Your recent sequences stay in this browser so you can follow each round. Another installation can use the shared ID to check the saved result. You can also preset an exact sequence for the next round; those results are clearly marked as manual.

Privacy and installation keys

This browser keeps a random installation key in a secure cookie so the service can keep your private history separate and prevent a public check from being opened by the same installation. It is not a hardware fingerprint. Clearing site data, using private browsing, or changing browsers creates a new installation key.
