This has been an age old problem for me. I resolved in ps7 (recently upgraded to cs3) by converting color profile to "color LCD" before saving for web. Yes, I know this means that colors are calibrated for my lcd. But my general experience is that it has been better than just doing "Save for web" in which case everything is muted. Now in CS3, I get muted no matter what. I've been working in sRGB period. I tried my old trick, which didn't do anything period. I've also tried saving with web with embedded color profile, "standard windows", "standard mac" etc and they all look the same - muted. Any ideas? My colors look so rich in photoshop, it's a shame to lose them on the web.
