Best Practices
Ratio: Text and interactive elements should have a color contrast ratio of at least 4.5:1.
Color blindness: Red/green color blindness is the most common, so avoid green on red or red on green. (Think especially about avoiding using red and green for “bad” and “good” indicators).
Web Elements:
Color as indicator: Color should not be the only indicator for interactive elements. For example, underline links on hover, or mark a required field with an asterisk.
