About WCAG contrast requirements
WCAG 2.2 Success Criterion 1.4.3 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px+ or 14px+ bold) at Level AA. Level AAA raises this to 7:1 for normal text and 4.5:1 for large text.
Low contrast affects roughly 1 in 12 men and 1 in 200 women who have color vision deficiency, plus anyone viewing screens in bright environments or using low-quality displays.
