Cool . . . I'm going to add that to my IE browser. Or is it a Windows program?
I already use the Firefox add-on called ColorZilla (available here: https://addons.mozilla.org/en-US/firefox/addon/271) which displays both hexadecimal and rgb formats for whatever you hover over...but not the little zoomed-in pixelated image that Instant Eyedropper shows, which is a nice feature.
Thanks Royster!
