The method
WCAG sRGB relative luminance and contrast ratio = (lighter luminance + 0.05)/(darker luminance + 0.05). Normal text AA threshold 4.5:1; large text AA threshold 3:1.
Limits and next steps
Solid-color pair checks only, not full accessibility certification. Large text is at least 18pt regular or 14pt bold. Sources: https://www.w3.org/TR/WCAG22/#contrast-minimum and https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum
