hi, I am learning the part named “applied accessibility”, and I feel confused about “contrast ratio”.
I check it on w3, and here’s the df: https://www.w3.org/TR/WCAG21/#dfn-contrast-ratio
But I cann’t figure out it. Here’s the question:
color: hsl(0, 55%, 20%);
background-color: hsl(120, 25%, 35%);
Current combination of a greenish background-color with maroon text color has a 2.5:1 contrast ratio.
- Why the contrast ratio is 2.5:1?
