Show WCAG AA and AAA ratios and thresholds

[snds]

It would be extremely useful to see how the values of each scale hold up against WCAG contrast accessibility standards for AA and AAA.

Additionally, it would be valuable to test against a specific color as well as the opacity value of the color. A number of design systems do this to inherit colors of an underlying swatch.

Hi @snds, I have added the new function to detect the WCAG AA and AAA ratios and thresholds(color), I put the link below, in case anyone also need it.
