Paint Mixer

Paint Mixer is a browser experiment by Amir Mušić in the lab section of his website. The page describes it as mixing your palette as thick paint: use a brush or a knife on the canvas, shape the paint's surface, and collect the new colors as CSS and JSON. There's a Pick / Paint toggle and a Mix tool, a HEX color input, controls for brush radius and paint load, Light & surface settings, two export buttons, Copy CSS and Download tokens, and Replay study to play the session back. The credits page says the pigment mixing uses the spectral method from spectral.js, conversion to the OKLCH color space uses Culori, and rendering uses three.js. On X, the author says he built Paint Mixer with Codex, without naming a model. What sets it apart is that it brings paint-mixing to web color work: colors build up and blend on the canvas, then export in formats a website can use directly.

Who it's for:designers and front-end developers who pick colors for websites and brands, and anyone who enjoys paint and color and wants to play for a while.

Before you start: open it in a browser with no install, sign-in or payment; the interface is in English. The page says All paint stays in this browser; that's the author's statement, and we haven't checked its network traffic. There's an option to pick colors from your screen, which may make the browser ask for screen capture permission; we haven't tried it. The page doesn't mention phone support, and we haven't tested one. We haven't checked mixing, the knife, replay or the exports one by one, and we can't promise the mixed colors match real paint. The libraries it uses, spectral.js, Culori and three.js, are MIT-licensed and the Manrope font is under the SIL Open Font License, but we found no open-source or reuse license for the work itself.
