# Visual Theme & Atmosphere

ClickHouse's interface is a high-performance cockpit rendered in acid yellow-green on obsidian black — a design that screams "speed" before you read a single word. The entire experience lives in darkness: pure black backgrounds (`#000000`) with dark charcoal cards (`#414141` borders) creating a terminal-grade aesthetic where the only chromatic interruption is the signature neon yellow-green (`#faff69`) that slashes across CTAs, borders, and highlighted moments like a highlighter pen on a dark console.

The typography is aggressively heavy — Inter at weight 900 (Black) for the hero headline at 96px creates text blocks that feel like they have physical mass. This "database for AI" site communicates raw power through visual weight: thick type, high-contrast neon accents, and performance stats displayed as oversized numbers. There's nothing subtle about ClickHouse's design, and that's entirely the point — it mirrors the product's promise of extreme speed and performance.

What makes ClickHouse distinctive is the electrifying tension between the near-black canvas and the neon yellow-green accent. This color combination (`#faff69` on `#000000`) creates one of the highest-contrast pairings in any tech brand, making every CTA button, every highlighted card, and every accent border impossible to miss. Supporting this is a forest green (`#166534`) for secondary CTAs that adds depth to the action hierarchy without competing with the neon.
