This template checks for compliance with [http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140916/G17 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 <code>base</code> colour value, and the tracking category, <code>category</code>, to place non-compliant transclusions in. A third parameter, <code>other</code>, 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 {{tl|Greater color contrast ratio}}.
== Examples ==
* {{#invoke:DemoTemplate|{{BASEPAGENAME}}|base=navy|category=Test}}
* {{#invoke:DemoTemplate|{{BASEPAGENAME}}|base=navy|other=|category=Test}}
* {{#invoke:DemoTemplate|{{BASEPAGENAME}}|base=navy|other=navy|category=Test}}
* {{#invoke:DemoTemplate|{{BASEPAGENAME}}|base=red|category=Test}}
* {{#invoke:DemoTemplate|{{BASEPAGENAME}}|base=#CC5500|category=Test}}
