Insufficient Contrast Between Foreground Text and Background
Textual content should have high contrast ratios against their backgrounds in order to be legible to your readers. Contrast ratios can be checked using WebAIM’s Contrast Checker.
- For Microsoft Office 365 users, highlight the segment of text that has the low-contrast issue.
- Change the font color of the text in the floating toolbar above the highlighted text. The option to change color is also available in the Ribbon.
Select a font color that pairs well with your background or highlight color.
