That's funny. Photoshop says it is 1c1c1c. those colors are pretty different if you look at the RGB values.
Dya think it might have something to do with what browser we are viewing the image in? I have noticed some browsers render colour differently. I'm using FF 2.0.0.4
I don't know how colorzilla works but I suspect that it is telling us what color the browser is displaying the image as, not as what color the image actually is. Photoshop on the other hand says what color the image actually is, if that makes any sense.
