WCAG 2.1 AA SC 1.4.3 Test for Color Contrast

This is a free color contrast analysis that will display the color contrast issues of a web page per WCAG 2.1 Guidelines. Color Contrast refers to how bright or dark colors appear against each other on screens; particularly with regard to the relative, gray-scale luminosity as perceived by the human eye.

When it comes to website accessibility, the contrast between the text and the text background is a concern for colorblind and other visually impaired users.
