Why Color Matters
About 1 in 12 men and 1 in 200 women experience some form of color vision deficiency (National Eye Institute, 2019). For these students, color alone may not communicate information effectively.
Color can add visual interest and help organize information, but if it is the only way to convey meaning, some students may miss important details. Accessible use of color ensures that all students, regardless of their ability to perceive colors, experience content in the same way.
How to Use Color
Color can enhance accessibility when used sparingly and with intention.

General Tips for Using Color
- Use color for visual emphasis, but always pair it with another cue, such as bold text, symbols, or labels.
- Ensure strong contrast between text and background. Aim for at least a 4.5:1 contrast ratio (WCAG 2.1 AA standard).
- In charts or graphs, combine color with other differences like shapes, patterns, or labels (e.g., circles, triangles, or diamonds) so categories remain distinct.
- Provide descriptions for figures that explain what the colors represent.
- Use Canvas’s Accessibility Checker, Panorama, or tools like the ones listed above to confirm color choices meet accessibility standards.
