HTMLColors

From Alberto Martinez Perez:

HTML Colors is a light color picker that displays the hexadecimal, decimal and RGB values of a color. It allows selecting colors and copying values directly from the taskbar icon, and can copy automatically the color code to the clipboard. You can set a global hotkey for selecting a color even when other applications are active, which combined with the auto-copy and auto-paste features allows integrating it with any editor. Also, you can have it on top of other windows for quick access (its compact interface takes up very little desktop space).
