Design System Inspiration of WeTransfer

1. Visual Theme & Atmosphere

"The simplest way to send big files? That's us. A platform to empower creatives while using business as a force for good? Also us." WeTransfer moves big files for millions of people a month and runs an editorial arm and a premium advertising space for brands. Its terms give a notice address at Nieuwezijds Voorburgwal 162, Amsterdam, the Netherlands.

The interface is plain and confident: white and light grey (#f9f9f9, #d6d6d6), near-black ink #161616, a charcoal neutral action #353535, and WeTransfer blue #3767ea for the product's base action. Type pairs GT Super WT for display with Actief Grotesque for text.

What makes it worth reading:

• Actions as families. --wt-color-{base, neutral, upsell, destructive}-{enabled, hover, active, tint} — four intents, each with three states and a tint.
• Full ramps with odd steps. --wt-color-blue-66, -gray-55, -red-65 — steps chosen for contrast, not round numbers.
• Darken tints as tokens. --wt-color-tint-darken-05 to -95, plus --wt-color-interaction-darken-light rgba(0,0,0,.05).

Primary tasks

• Send or request files; sign up or log in.
• Explore features, pricing and use cases.

4. Component Stylings

Measured with focus under a real Tab key and a hover counted only when :hover matched. Cookie consent rejected; a terms-agreement dialog was never answered.

• Sign up — #353535, #f1f1f1 14px/500, 8px, 32px. Hover #464646 (white label), press #161616; focus a 4px #464646 ring.
