Color contrast and WCAG: how to fix hard-to-read text

Light gray text on white is the most common accessibility problem in AI-generated apps. Learn the WCAG contrast rule and how to fix it in your theme.

Why it happens

WCAG 1.4.3 requires a contrast ratio of at least 4.5:1 between text and background (3:1 for large text). Below that, text is hard to read for people with low vision, and for anyone using a phone in sunlight.

AI-generated templates love light gray secondary text, faded placeholders and soft-colored buttons. It looks great on the designer's screen and is unreadable in the real world.

How to check your app

1. In Chrome, open DevTools, select some text and check the contrast ratio in the color picker.
2. Extensions like axe DevTools list every element with insufficient contrast.
3. Launch Check runs axe-core on your pages and counts how many elements fail.

How to fix it

Adjust colors to at least 4.5:1 contrast for normal text and 3:1 for large text (WCAG 1.4.3). Fix it in the theme color tokens, not element by element.
