LaunchDarkly pairs geometric Sora at 80px/700 with Söhne at 16px on charcoal #191919, then detonates lime #DDFF46 buttons against it — feature-flag risk management styled like a rave flyer for platform engineers. Product panels stack release, AI-config and observability UI in tight cards; the asymmetric bottom-rounded button corners are the tell that the system sweats details.

# LaunchDarkly — Design System

> dark, modern, high, custom

LaunchDarkly pairs geometric Sora at 80px/700 with Söhne at 16px on charcoal #191919, then detonates lime #DDFF46 buttons against it — feature-flag risk management styled like a rave flyer for platform engineers. Product panels stack release, AI-config and observability UI in tight cards; the asymmetric bottom-rounded button corners are the tell that the system sweats details.

**Using these colors**

- **Action color** `#DDFF46` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#DDFF46` — one role, not several (your action color).
- **accent** `#DDFF46` — 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.
- **link** `#FF9D29` — inline text links and link-styled controls.
- **secondary** `#405BFF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
