This template checks for compliance with WCAG G17, i.e. that a background–foreground colour combination has got a contrast ratio of more than 7:1. It takes two arguments, the base colour value, and the tracking category, category, to place non-compliant transclusions in. A third parameter, other, is optional; the template will by default calculate the contrast ratio against black and white, on the assumption that it is used in conjunction with {{Greater color contrast ratio}}.
