Connect the Color Converter Engine to your AI client once. After that, you can just drop hex codes into your chat to check readability.

Ask AI about this page

Short answer

Can my AI check if text is readable?

Yes. Your AI uses brightness detection to determine if black or white text provides enough contrast against a background color. You'll get a clear answer on whether your text is legible or needs adjustment.

The results

What you get from the AI

The AI processes your color inputs and gives you these specific outcomes.

PASS

Legibility confirmed

The AI detects sufficient brightness difference. You get a confirmation that your text color works on that background.

FAIL

Contrast warning

The AI finds the colors too similar. It tells you the text is unreadable and needs a different shade.

DECISION

Black or white choice

The AI evaluates both options. It tells you which specific text color is the better fit for your background.

HUMAN

Manual design tweaks

The AI identifies the problem, but you decide the final brand colors. You handle the actual CSS or design updates.

The workflow

What your AI does when the color data arrives.

The AI handles the math so you don't have to look up contrast ratios manually.

  1. Receive hex codes

    You provide the background and text colors in hex format. The AI receives these values to begin the analysis.

    convert_color
  2. Calculate brightness

    The AI runs brightness detection on the provided colors. It determines how much light each color reflects.

    convert_color
  3. Compare contrast

    The AI compares the brightness of the text against the background. It checks if the difference is large enough for readability.

    convert_color
  4. Deliver verdict

    The AI sends a plain text response. It tells you if the combination passes or fails the readability test.

    convert_color
