Usage

The Template:Color contrast conformance gives a "AAA", "AA" or "none" judgment for the level of conformance to WCAG 2.0 of two colors together, in terms of contrast ratio, where the colors can be either RGB #numbers (#56F3BB) or color names (green, darkorange, or NavahoWhite, etc.).

Code	Result
{{Color contrast conformance|blue|white}}	Contrast: blue & white, conformance level= AAA
{{Color contrast conformance|red|#FFcc00}}	Contrast: red & #FFcc00, conformance level= none
{{Color contrast conformance|black|White|show=no}}	AAA

Either parameter 1 or 2 can be a standard color name (in upper/lowercase letters) or an RGB #number, such as: #FF45BB. See: Web colors, for a full list of color names and the assigned RGB #number values. The option "show=no" will suppress showing the color names or numbers, and give just the "AAA", "AA" or "none" answer.
