Ensuring Color Contrast

Use appropriate color contrast and font sizes.

Contrast is the difference between text color and background color.

Use online contrast checker tools to test combinations.
Minimum contrast ratios:
- 4.5:1 for normal text
- 3:1 for large text (18pt+ or 14pt+ bold)

This includes the use of Detroit Mercy's color palette combinations and neutral colors. Please visit Detroit Mercy Visual Identity to view our color combination examples.
