Color Replacer от ICodeBugs

Collects all colors shown on the page the user visits.
- Searches for <code>color</code>, <code>background-color</code>, and <code>border-color</code> (not gradients and images)
- Features an invert colors button to invert all colors on the page
- Does not save, reload the page to reset settings

Note: this extension struggles with highly stylized or pages which have their colors changed dynamically.
