What AI agents can do with WCAG Contrast Checker: 3 Tools for Web Color Compliance

Use these tools to validate palettes, calculate exact ratios, or suggest compliant colors so your design passes all accessibility checks.

Audit palette

Validates whether an entire set of colors meets a specific accessibility standard.

Calculate contrast

Determines the precise contrast ratio and if two specified colors are accessible.

Find compliant suggestion

Suggests a new background color that meets your target standard by adjusting the lightness of the current color.

Frequently Asked Questions

How does WCAG Contrast Checker help me meet accessibility standards? +

It gives you immediate, precise data on color ratios. Instead of guessing if two colors are readable, it calculates the exact contrast ratio and tells you if they pass specific levels like AA or AAA, making compliance straightforward.

Can I use this MCP to check my entire website's color palette? +

Yes. You can run an audit on a whole set of colors using the MCP. This helps you verify that every single background and foreground combination across your site meets compliance standards before development even starts.

If my text fails the test, what should I do? +

The MCP has a tool that suggests specific alternative colors for backgrounds. It adjusts the lightness of the failing color just enough to get you back over the required AA or AAA threshold.

Is this better than using browser extensions for contrast checking? +

This MCP is much more powerful because it’s programmatic. You aren't limited to what a single extension can check; your AI agent uses it to run comprehensive, multi-point audits and suggestions across entire design systems.

Does WCAG Contrast Checker support the newest APCA standards? +

Yes. It supports both the established WCAG 2.1 rules and the newer APCA models (WCAG 3.0), giving you future-proof validation for your designs.
