The term “color contrast” describes the difference between text and the background. Low contrast affects readers with low vision and color blindness.
Tips for Color Use
- Choose a color scheme that provides high contrast between the text and the background. If you have a dark background, the text should be light, and vice versa. (Black and white provide maximum contrast.)
- Avoid the following color combinations:
- Green and gold from the CSU brand should not be used for text (use this combination for decoration only).
- Green and red (or related colors)
- Blue and yellow (or related colors)
- Use larger text and simple (not ornate) fonts. Sans serif fonts are preferable.
- Use a contrast checking tool. We recommend the Colour Contrast Analyser by the Paciello Group.
- If you are building a webpage, check it with a color blindness simulation tool.
- Don’t rely on color as the sole means of conveying information. For example, don’t use color as your only method of indicating heading levels.
- Text can be difficult to read on photographic or gradient backgrounds. Set text against a solid background when possible.
