Run Color Converter Engine inside Claude Desktop

The `convert_color` tool translates raw color strings into HEX, RGB, HSL, and CMYK formats inside Claude Desktop. It runs locally via stdio, meaning your design values stay right on your machine instead of bouncing through third-party APIs. You do not need to look up color charts anymore. The tool tells Claude Desktop if a color is light or dark, giving your agent the exact context it needs to build readable UI components on the fly.

Get precision CSS Level 4 values instantly

The `convert_color` tool provides CSS Color Level 4 precision directly to your active chat workspace. This MCP Server solves layout bugs by translating named colors like tomato or cornflowerblue into exact mathematical formats. Your agent uses the output to write pixel-perfect CSS. Instead of manual copying and pasting from external web tools, you get the exact alpha channels and luminance values inside your active workspace.

Build readable dark mode themes on the fly

Calculating luminance and accessibility values is handled by the `convert_color` tool. The engine calculates contrast and automatically flags whether a color is light or dark, helping Claude Desktop make smart decisions when generating themes. You can ask your agent to adjust a color's HSL values until it hits your target contrast ratio. No more trial and error with online contrast checkers while building your layout.
