This extension does technically work. However, it seems unfinished. When I use it to identify a color on a webpage, it first gives me a series of three popups that seem to be in place for debugging purposes. After I close each popup, I am able to see the hex code for the color I picked. When I dismiss the hex code, I see the same three debugging popups again. This is obnoxious and makes me not want to use the extension.

Additionally confusing - the extension's logo once installed is different from the logo on this page, which does not inspire confidence.
