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.
Insufficient Contrast Between Foreground Text and Background
- For Microsoft Office 365 users, highlight the segment of text that has the low-contrast issue.
- Change the font color in the floating toolbar above the highlighted text, also accessible via the Font menu in the Ribbon’s Home tab.
- Select a font color that pairs well with your background or highlight color.
