How CHROMA WORKS
was made.
Signature technique: Interactive OKLCH mixing laboratory. The page is one dependency-light HTML document with embedded styles and scripts; this guide is a second self-contained document using the same visual language.
Build sequence
Write values directly into OKLCH CSS.
Compute contrast against black and white.
Announce live values to assistive technology.
Reproduce it
Copy the parent index.html, preserve the semantic landmarks, then isolate the render loop from the content layer. Keep canvas and 3D surfaces aria-hidden; the story must remain complete without them. Cap device pixel ratio at 2 for expensive scenes, listen to prefers-reduced-motion, and test the final composition at 375px before publishing.
Why this technique
Interactive OKLCH mixing laboratory is not decoration here: it carries the site's central metaphor. That alignment between subject and mechanism is what keeps a technical showcase from becoming a demo reel.
