Color Contrast Checker

Good design isn’t just about looking great; it’s about being readable. Most contrast checkers only let you test two colors at a time. This tool generates a complete visibility map, showing you exactly how every color in your brand palette performs as both a background and a text element. Whether you are building a website or a mobile app, this matrix helps you eliminate “guessing” and replace it with data-driven design decisions.

Guide: How to use this tool?

Using this Accessibility Contrast Matrix is the easiest way to ensure your brand colors are readable and compliant with international accessibility standards (WCAG).

Here is a simple guide to getting the most out of the tool.

1. Choose Your Color Count

Start by deciding how many colors you want to test at once.

• Locate the “Number of Colors” dropdown at the top.
• Select between 2 and 6 colors. The matrix below will automatically expand or shrink to match your choice.

2. Enter Your Colors

You can input your brand colors in three different ways. The tool keeps all of them in sync for you:

• The Color Picker: Click the colored square (swatch) to open a visual palette and pick a color manually.
• HEX Code: Type or paste a hex code (e.g., #0055FF) into the HEX box.
• RGB Values: If you have RGB numbers (e.g., 255, 255, 255), enter them in the RGB box.

3. Read the Results (The Matrix)

The matrix shows how every color in your list interacts with every other color.

• The Rows (BG ↓): Represent the Background color.
• The Columns (TXT →): Represent the Text color.
• The Intersection: This shows exactly how that specific text color looks on that specific background.

4. Understand the Scores

Inside each cell, you will see a Contrast Ratio number and a Status Label. Here is what they mean:

Status	Ratio	What it means
AAA	7.0 or higher	Enhanced Contrast. Highest accessibility; safe for all text sizes.
AA	4.5 to 6.9	Standard Contrast. Good for body text and general reading.
Fail	3.0 to 4.4	Partial Pass. Only safe for very large text or UI components like buttons.
Fail	Below 3.0	Poor Contrast. Do not use these colors together for text.

5. Export Your Report

Once you’ve found the perfect combinations, you can save your work for your design handoff or style guide:

• Save as Image: Downloads a .png file of your current matrix.
• Save as PDF: Generates a professional PDF document of your results.

Pro Tip:

If a combination shows a “FAIL,” try slightly darkening your text color or lightening your background color until the label switches to AA. Even a small adjustment can make your palette usable for everyone!
