Template:Colour style/doc

{{#invoke:Message box|mbox}}

This template is for use with {{Infobox individual biography/style}}. It should not be used directly.

Usage

• {{Roleclass colour|roleclass|1}} for the primary colour
• {{Roleclass colour|roleclass|2}} for the secondary colour
• {{Roleclass colour|roleclass|3}} for the tertiary colour (if different from the primary)

Note, it is important that the primary and secondary color have sufficient contrast to be readable when used as the background and font color. This is especially important for readers with visual impairments. You can check the contrast using {{color contrast ratio}}. A ratio of greater than 4.5 or less than 0.22 is sufficient, but the larger or smaller the better.
