To find instances of color-coding, visually scan your document. People who are blind, have low vision, or are colorblind might miss out on the meaning conveyed by particular colors.
Here are some ideas to consider:
Add an underline to color-coded hyperlink text. That can help colorblind people know the text is linked even if they can’t see the color.
Add shapes if color is used to indicate status. For example, add a checkmark symbol
if green is used to indicate “pass” and an uppercase X
if red indicates “fail”.
