TintedTags

This plugin is to be used with acts_as_taggable_on. TintedTags allows you to create a tag cloud where tag popularity is illustrated with colour. It achieves this by adding a :tint attribute to the Tag model, and allows you to calculate a colour (in the form of a hex code) for each tag based on its popularity. These hex codes are added to the tags in the view via inline-css.

Tags are updated via an after_save filter on a TintedTags object.
