I've dealt with this before but cannot recall how I fixed it. I'm pulling the examples from http://www.element87.com. Using the eyedropper tool via Photoshop CS, the background color for the image is #D0D0D0 (http://www.element87.com/index.png - feel free to check for yourself) Using CSS, I've set the background color for the page to be #D0D0D0 Given that information, the image background and background color of the page should match. Screenshot from Mozilla Firebird (latest nightly OS X build): Screeenshot from Safari v1.1: Screenshot from IE 5.2: As you can tell, they like to use their own palettes of colors :blink: Safari is the only browser that renders the page properly; the others alter the background color to different color. I have a hunch it has something to do with not using websafe colors and some browsers using web-safe palettes while others (i.e. Safari) don't.
