Template:Rarity

Renders a rarity band in the colour the game uses for it.

{{Rarity|Legendary|legendary}}

The first parameter is the label shown to the reader; the second is the CSS slug, because two bands ("Epic Untiered", "Item Set") contain a space and a class name cannot. Both come from Wiki-src/CosmicWikiBot/Rarity.cs, which is the one place a band is defined, and the colours live in MediaWiki:Common.css.

This template deliberately does not add a category. It is used on list pages as well as item articles, and a category here would file every list under every rarity.
