Usage
To use this module, you may use one of the above listed templates or invoke the module directly
- To compute relative luminescence:
{{ColorToLum|color}}or{{#invoke:Color contrast|lum|color}} - To compute a contrast ratio between two colors:
{{Color contrast ratio|color1|color2|error=?}}or{{#invoke:Color contrast|ratio|color1|color2|error=?}} - To determine which of two colors (color2a and color2b) has the greater contrast ratio with a particular color (color1):
{{Greater color contrast ratio|color1|color2a|color2b}}or{{#invoke:Color contrast|greatercontrast|color1|color2a|color2b}} - To compute the contrast ratio between the background and text colors specified in a css style string:
{{#invoke:Color contrast|styleratio|css style statement string|default background color|default text color}}
