Color Contrast

For websites, color contrast typically refers to the difference between the background color and the foreground color (usually font color). This difference has implications for readability and accessibility. Online contrast checker tools can be used to verify different background/foreground combinations and check their accessibility.

  1. Foreground text and background need to follow WCAG 2.0 level AA compliance where a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is needed.
