RNV Color MCP server

This is a helper for anything color related. You can ask your AI to mix two paint colors, convert a hex code, check if text is readable on a background, or save a set of colors under a name you choose. It is handy if you work with design, branding, or just want to stop guessing what colors go together.

What this MCP server does

You type a request in plain words, like mixing two colors or saving a palette. Your AI reads it and calls this helper with the right details. The helper does the exact color math, converts between formats, or looks up a color name. Then it sends the answer back, and your AI shows it to you in the chat. If a color name does not exist or a value is out of range, it tells you instead of guessing.

• “Save a palette called Spring line with near-black and brand gold”
• “Give me three complementary accents for my Spring line palette”
• “Is white text readable on this dark blue background”

What it gives back to you

You get answers right in the chat. Sometimes it is a single color value like a hex code. Sometimes it is a small list of colors, like a harmony set or the swatches in a saved palette. For contrast checks you get a ratio and a pass or fail. When you save a palette, it confirms the name and tells you whether the save will last.
