Contrast ratio is a measure of the difference in perceived brightness between two colors. The higher the ratio, the better the contrast.
According to Web Content Accessibility Guidelines (WCAG) 2.0, text and images of text should have a minimum contrast ratio of 4.5:1 (Level AA), while large text should have minimum contrast ratio of 3:1. For enhanced contrast (Level AAA), normal text and large text should have minimum contrast ratio of 7:1 and 4.5:1 respectively.
