Segment signs off in Whitney SSm at 48px/700 — 'Segment ❤️ Twilio, we're finally moving in together' — with 16px body and blue #1866EE full-pill CTAs.

# Segment — Design System

> light, professional, medium, custom

Segment signs off in Whitney SSm at 48px/700 — 'Segment ❤️ Twilio, we're finally moving in together' — with 16px body and blue #1866EE full-pill CTAs. Unified-profile diagrams in Twilio's palette complete the merger story; a CDP brand gracefully dissolving into its parent, in its parent's humanist type.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFF0F1` |
| border | `#D8DADE` |
| text | `#000D25` |
| text_muted | `#606877` |
| primary | `#191F36` |
| accent | `#1866EE` |
| link | `#000D25` |
| secondary | `#1866EE` |
| button_bg | `#1866EE` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#1866EE` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary`, `button_bg` are all `#1866EE` — one role, not several (your action color).
- **accent** `#1866EE` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#191F36` — a brand color — but the call-to-action uses #1866EE, not this.
- **link** `#000D25` — inline text links and link-styled controls.
