How to fix it:
The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Note: Contrasts are not relevant where content is hidden. But make sure that for hidden content, which becomes visible when receiving focus, the contrast ratio is sufficient. Insufficient contrast between text and its background can give problems for users with low vision and colour blindness, but it can also affect a lot of other users, leading to important text potentially being overlooked.
