WCAG 2.1
Version 2.1 of the Web Content Accessibility Guidelines published by the World Wide Web Consortium (W3C), which provides specifications for web content accessibility. Criterion 1.4.3 requires a contrast ratio of at least 4.5:1 for normal text and at least 3:1 for large text to pass at level AA.

WCAG 2.1 is version 2.1 of the Web Content Accessibility Guidelines published by the W3C, in which clause 1.4.3 requires body text to have a contrast ratio of at least 4.5:1 and large text (roughly 18pt or 14pt bold and above) at least 3:1 in order to pass level AA.
Contrast is calculated from relative luminance, ranging from 1:1 to 21:1, with a formula that involves first applying gamma correction to each sRGB channel and then computing a weighted sum.
The contrast ratio between the focus indicator and the immediately adjacent background should be at least 3:1, a threshold that comes from the WCAG 2.1 1.4.11 Non-text Contrast criterion.
Success Criterion 2.3.3 of the WCAG 2.1 standard requires websites to comply with the "Animation from Interactions" guideline and to respect the prefers-reduced-motion preference setting.
