Frequently asked questions

Is #CCCCCC on #1A1A1A accessible?

Large text (18pt+ or 14pt+ bold) needs only 3:1, so this combination passes for headings and large UI labels. AAA conformance demands 7:1; this combination passes that bar.
Where is this combination commonly used?

How is this ratio calculated?
WCAG 2.1 contrast ratio is (L1 + 0.05) / (L2 + 0.05) where L1 and L2 are the relative luminances of the lighter and darker colors. Each channel is gamma-corrected (linearized) before applying coefficients 0.2126·R + 0.7152·G + 0.0722·B. The two formulas weight green most because the human eye is most sensitive to green wavelengths.
