Why Red for your UI?

Red is the color of energy, urgency, and passion. While often used for errors and warnings, a carefully crafted red-based system can be powerful for entertainment, food, sports, and any product that wants to evoke excitement and immediate action. The key is balancing intensity with enough neutral space.

FAQ

What colors pair well with red?
Our generator automatically creates a complementary accent color (hue +120°), balanced text colors, and neutral backgrounds. The entire system is derived mathematically from the red base to ensure harmony.
Is a red color system good for dark mode?
Absolutely. Our generator creates optimized dark and light mode variants. In dark mode, the red primary maintains vibrancy against dark backgrounds, with adjusted surface and text colors for readability.
Can I customize the red palette after generating it?
Yes! The generated palette is a starting point. You can use our tool to pick any shade of red as your base, and the entire system adapts. You get CSS variables that are easy to override.
