Short answer

How do I check color contrast accessibility with my AI?

Your AI uses luminance detection to see if a background color supports readable text. It calculates the contrast ratio for any hex code you provide. You'll see the specific results for your color pairs below.

The results you get.

Where your data lands.

The AI processes your color inputs and delivers these specific outcomes.

PASS

Accessible color pairs

The AI confirms when your text and background colors meet readability standards. You get a clear signal that the pair is safe to use.

FAIL

Inaccessible color pairs

The AI identifies when contrast is too low for readability. It flags these specific combinations so you can avoid them.

DATA

Luminance values

The AI provides the mathematical luminance values used for the check. This gives you the raw data behind the contrast ratio.

HUMAN

Final design choices

The AI identifies the problem, but you decide which new colors to pick. You choose the final palette based on the feedback.

The workflow

What your AI does when you provide color codes.

The AI handles the math so you don't have to manually calculate luminance.

  1. Receive hex codes

    Your AI takes the hex codes or color names you provide in the chat.

    convert_color

  2. Calculate luminance

    The AI runs the math to find the relative luminance of each color.

    convert_color

  3. Determine contrast

    The AI compares the two luminance values to find the contrast ratio.

    convert_color

  4. Report accessibility

    The AI tells you if the pair passes or fails based on the ratio.

    convert_color

FAQ

How this task behaves.

  • 01

    Can the AI change my CSS files directly?

    No. The AI only checks the colors and provides the results. You must manually update your code or design files.

  • 02

    Does it check for WCAG compliance?

    Yes, the AI uses luminance detection to determine if the contrast ratios meet standard accessibility requirements.

  • 03

    Can I use color names instead of hex codes?

    Yes, as long as your AI client can resolve the color name into a value the tool can process.

  • 04

    Will the AI suggest new color palettes?

    The AI can suggest colors that pass the check, but it does not automatically generate full brand palettes.

  • 05

    Does this work with any color format?

    The tool relies on the ability to convert the input into luminance values, typically using hex codes.
