I talked to gerbick about this..
I was creating this color in photoshop #E5552F, it displays fine in photoshop but when i try to save it as a JPEG from photoshop in the preview the color changes to #E65631 (this alteration happens all all non black/grey colors), i tried this in windows and got no color change. I was wondering if this is just another CS in Tiger problem? I'm planning on upgrading to CS2 sometime soon.
