Encyclopedic overview
To use a colour in a template or table you can use the hex triplet (e.g. #CD7F32 is bronze) or HTML colour name (e.g. red).
Editors are encouraged to make use of tools, such as Color Brewer 2 to create Brewer palettes, listed at Wikipedia:Manual of Style/Accessibility § Color for colour scheme selection used in graphical charts, maps, tables, and webpages with accessibility in mind for colour-blind and visually impaired users.
