Overview

Two MCP servers for color-vision accessibility. They check whether a palette or image is colorblind-safe and produce recolored versions simulating protan, deutan, and tritan vision. Uses the Machado 2009 method with CIEDE2000 color difference, runs locally via stdio.

Best for
Developers building colorblind-safe interfaces who want local MCP-based accessibility checks.

Use cases

• Validate a UI palette for colorblind safety
• Generate protan, deutan, and tritan simulations of an image
• Integrate color accessibility checks into an MCP-compatible workflow

Use cases

• Validate a UI palette for colorblind safety
• Generate protan, deutan, and tritan simulations of an image
• Integrate color accessibility checks into an MCP-compatible workflow

Pros

• Uses a published, cited method (Machado 2009 plus CIEDE2000)
• Covers all three common color vision deficiencies
• Runs locally via stdio, no network dependency

Cons

• No stars or community adoption yet
• Limited to JavaScript ecosystem
• Requires MCP client setup to use
