How to calculate colour contrast – ADG – Accessibility Developer Guide
To calculate the contrast ratio, the relative luminance of the lighter colour (L1) is divided through the relative luminance of the darker colour (L2): (L1 + 0.05) / (L2 + 0.05) This results in a value ranging from 1:1 (no contrast at all) to 21:1 (the highest possible contrast). While high contrast is generally good, higher is not always better.
