Every time you ask an AI to convert #ff5733 to HSL, you get a different answer. Sometimes close, sometimes wildly wrong. That's because LLMs don't do math — they predict tokens. This MCP eliminates the guesswork entirely.

Powered by colord (4M+ weekly downloads), every conversion is mathematically exact to the CSS Color Level 4 specification. One input, all formats returned simultaneously.

The Superpowers

  • All-in-One Conversion: Pass any color once — get HEX, RGB, HSL, CMYK, and the closest CSS named color back instantly.
  • Dark/Light Detection: Know instantly if a color needs white or black text on top, with exact brightness values.
  • 148 CSS Names: Automatically maps any color to its closest named equivalent — no more guessing 'is this salmon or coral?'.
  • Alpha Channel: Full transparency support with rgba(), hsla(), and 8-digit hex.

I'm designing a dashboard. Convert the brand color #2563eb to all formats so I can use it in CSS, Figma, and print.

HEX: #2563eb | RGB: rgb(37,99,235) | HSL: hsl(221,84%,53%) | CMYK: cmyk(84,58,0,8) | Name: royalblue | isDark: true

Is the background color #1a1a2e dark enough for white text?

isDark: true | brightness: 0.09 | White text will be highly readable on this background.

My designer sent me rgb(240, 128, 60). What's the closest CSS named color I can use as a shorthand?

Closest named color: 'coral' | HEX: #f0803c | Full RGB/HSL/CMYK breakdown included.

LLMs predict tokens, they don't do math. Ask the same conversion 3 times and you'll get 3 different HSL values. This engine uses the actual CSS color math — same input, same output, every time.
