Replicate. Golden hour API workshop.

Replicate projects a sunlit developer playground on white: one signature sunset gradient (magenta → ember → gold) anchors the hero, section borders, and brand moments, while every interactive surface dissolves into a pill (9999px radius). The system pairs a high-contrast display face (RB Freigeist Neue, up to 128px) for editorial headlines against Basier Square at 14–16px with -0.025em tracking for functional UI — two voices, one warm-white canvas. Code is first-class: GitHub-syntax editor cards live directly inside marketing layouts, not buried in docs. Color discipline is severe: nearly the entire interface is #202020 on #ffffff, with a single ember accent (#ea2804) appearing only inside the gradient and the logo mark. Shadows are essentially absent — flat surfaces and 1px hairline borders carry the elevation language instead.

Replicate

Brand1

  • Hero background wash, section border frames, brand-mark dot grid — the only chromatic surface treatment in the system. Always at full saturation; never desaturated or muted; The single non-gradient accent — appears in the logo mark and the warm shadow tint. Never used for buttons, links, or text; its job is to anchor the gradient's red midpoint

Accent1

  • Green supporting accent for decorative details and low-frequency emphasis. Use as a supporting accent, not as a status color

Neutrals9

  • True black for the logo wordmark, high-contrast icon strokes, and maximum-impact filled buttons when Ink is insufficient

  • Supporting neutral for secondary UI, dividers, and muted labels. Do not promote it to the primary CTA color

  • Secondary text, metadata, run counts, helper labels. Provides a quiet middle step between Ink and the silver border tones

  • Avatar ring borders, decorative shadow tint, inactive dividers

  • Hairline borders on cards, model tiles, and input fields. The primary structural divider color

  • Subtle surface step (alt card backgrounds, section bands), input field default state

  • Warm-white off-state surface used for the secondary surface tier (e.g. model card backgrounds behind thumbnails)

  • Rare warm-tinted surface used inside editor cards and callout blocks — a very subtle nod to the gradient's yellow endpoint

  • Page canvas, card surfaces, code editor background. The base layer everything sits on
