[From The Mysterious “Save For Web” Color Shift | Web Design Blog: Web Design & Innovation in web standards : Viget Labs]

I’ve had the mysterious Photoshop to Save For Web colorshift for sometime, which has really screwed up some of my website designs, because I couldn’t reconcile the colors I was using inside photoshop with the colors the colors that I was getting in Save for web. Finally I figured it out thanks to this helpful tutorial by Doug Avery, who looks like he was the designer of Odeo, which I always liked their site design. This will save me from a multitude of future headaches.
