Reference fixture · claude

Thoughtful conversations, made tangible.

A warm, literary design system built on parchment — where every interaction carries the weight of a considered reply.

What this fixture exercises

Warm parchment, terracotta, and the gentlest possible containment.

Parchment surface tokens

--bg (#f5f4ed) → --surface (#faf9f5) → --surface-warm (#e8e6dc). Three warm tiers with yellow-brown undertones — no cool grays anywhere.

Terracotta discipline

--accent (#c96442) appears only on the primary CTA and brand moments. The warm sand secondary button keeps the screen from feeling mono-terracotta.

Serif/sans hierarchy

Anthropic Serif weight 500 for all headings — the single weight gives every title the gravitas of a published title. Anthropic Sans handles UI text with quiet efficiency.

Form components

Inputs in the same warm context.

Focus rings use Focus Blue (#3898ec) — the ONLY cool color in the entire Claude system. It exists purely for accessibility. Everything else stays warm.
