Ensure text and visual elements have adequate contrast so content can be read by all users.
Impact
Poor color contrast makes content difficult or impossible to read, especially for users with low vision or color blindness. Color should never be the sole method for conveying meaning.
How To
- Use Canvas’s accessibility checker.
- Ensure text stands out clearly from the background.
- Provide additional indicators besides color.
Things to Avoid
- Low‑contrast combinations.
- Images with unreadable text.
- Using color alone to indicate meaning.
