real render · source of truth

uber.com is built on a pure-white canvas (rgb(255,255,255)). The system uses rgb(255, 255, 255) as the singular interactive color. Fully-rounded CTAs (999px) signal a friendly, tactile interaction model alongside UberMove as the primary typeface. A restrained elevation system (3 distinct shadows) — shadows reserved for the few elements that must lift off the page. Interactions are smoothed by transitions across many elements, with little or no keyframe animation.

Do's & Don'ts

16 enforceable rules pulled verbatim from the spec

Use the extracted shadow patterns for elevation — they are tuned to match the brand palette

Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles)

Use Pure White (`#ffffff`) as the primary accent — it's the brand's signature interactive color

Use pill-shaped radius (999px) for primary CTA buttons — the brand uses fully-rounded, pill CTAs

Keep navigation sticky to the top — the design uses a persistent navigation pattern

Maintain nav height at 64px — consistent vertical space for the navigation bar

Build the hero as a split layout with media on the left — text and visual share equal weight

Include exactly 3 CTAs in the hero (primary + secondary) — this design pattern is multi-action, not single-purpose

Make the navigation sticky — it stays visible during scroll, signaling content depth

Use a 6-column grid on desktop — density matters for this content type

Repeat the primary CTA across 8 banner sections — conversion paths are layered, not single

Don't

Don't invent new shadow values — use only the extracted shadow levels

Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements

Don't introduce additional saturated accent colors — the palette is intentionally controlled

Don't use rectangular buttons for primary actions — the rounded pill shape is the brand standard

Don't collapse or hide the nav on scroll without an explicit scroll-triggered animation — the design uses fixed nav presence
