Usage
[ᥛᥥᥰ ᥗᥖᥴ ᥒᥝᥲ ᥒᥣᥱ]This template checks for compliance with WCAG G17, i.e. that a background–foreground colour combination has got a contrast ratio of more than 4.5:1. 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}}.
Note: this is compliant with AAA for 18 point or 14 point bold text.
| Rating | Normal text | 18 point or 14 point bold text |
|---|---|---|
| AA | 4.5 | 3 |
| AAA | 7 | 4.5 |
