# Claude — Style Reference
> A warm-canvas editorial interface for Anthropic's Claude product. The system anchors on a tinted cream canvas with serif display headlines, warm coral CTAs, and dark navy product surfaces (code editor mockups, model showcase cards). Brand voltage comes from the cream/coral pairing — deliberately warm and humanist where most AI brands use cool blue + slate. Type voice runs a slab-serif display ("Copernicus" / Tiempos Headline) for h1/h2 and a humanist sans for body. The signature Anthropic black-radial-spike mark anchors the wordmark.

## Do's and Don'ts

### Do

- Use `--color-primary` for the brand's primary interaction treatment.
- Keep page surfaces anchored to `--color-canvas`.
- Preserve every typography style's documented size, line height, and letter spacing.
- Compare major implementation decisions against [the live Claude website](https://claude.ai/).

### Don't

- Do not introduce colors outside the documented color token set.
- Do not replace `--color-ink` with an arbitrary neutral.
- Do not flatten documented component states or spacing relationships.
- Do not treat this extracted snapshot as newer than the live source website.

## Layout

Use the documented spacing scale and component geometry as the implementation baseline. Validate responsive composition and current page rhythm against [the live source](https://claude.ai/).
