What color mode are you using in Photoshop?
I'm in RGB color mode.
It's still a color profile issue. Photoshop uses them, Fireworks does not.
Since the vast majority of Web browsers don't use color profiles, Fireworks more closely shows your work as it will be seen.
Thanks for the reply - does that mean that I can't adjust how it looks in Fireworks? I tried to overcorrect it in Photoshop in hopes that it would look ok when I copied it into Fireworks, but the results were not satisfactory.
I remembered an article someone once linked to from here. Finally found it! http://www.viget.com/inspire/the-mysterious-save-for-web-color-shift/
Do please read the comments as there are other people with other approaches and still others who object strenuously to the method in the article. This is one of those issues with dedicated purists on both (many?) sides.
I don't use Photoshop much, so it's the best I can do for you, sorry!
