{{Lua|Module:Color contrast}}<!-- via Template:Color contrast ratio -->

== Usage ==

The '''[[Template:{{BASEPAGENAME}}]]''' 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 color model|RGB]] <code>#numbers</code> (<code>#56F3BB</code>) or color names (<code>green</code>, <code>darkorange</code>, or <code>NavahoWhite</code>, etc.).

|-
| {{tlx|{{BASEPAGENAME}}|black|White|show{{=}}no}} || {{{{BASEPAGENAME}}|black|White|show=no}}
|}

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