colorexa

A simple tool to lookup for colors specified as an RGB triplet in hexadecimal format. The background of the pop-up bubble refreshes automatically to represent the color typed in its text field or highlighted in the page. Supports full (six-digits) and abbreviated (three-digit) hexadecimal color codes. Useful when you want to quickly check a color found in the source code of a page or stylesheet.
