Finding hex code of colour in image

[lesliek19]

I would like to match some text on a web page to a particular colour in an image on that page.

Does there exist a Linux application that would allow me to place my mouse cursor over a point in the image and be told the hex code for the colour at that point?

Thanks for reading this,

Leslie

The ColorZilla (http://www.iosart.com/firefox/colorzilla/) Firefox extension will do that.

Thank you very much for directing me to ColorZilla. It worked as advertised.

Thanks again,
