Who's proficent with Adobe CS3 color management?

[IPT]

Okay, so I have this color management issue going on. I am using PSCS3 and Dreamweaver CS3. I have an image that lays over a background on a webpage. The image has the same color background as the page so it blends seemlessly.

I changed the image itself today (keeping the BG color the same). When I go to save for web (doesn't matter if I use JPG, PNG, or GIF) it shifts the color. The original file is viewed as RBG/8bit.

So here is the kicker. I finally got frustrated and just saved the file as a PSD within the folder of the "site" (in DW). Then I linked to the PSD image thru Dreamweaver. It (DW) then automatically saved it as a GIF and the color integrity was maintained correctly (no shift).

So, what is going on here? Clearly I am not looking at this image in the color space I think I am (or so it would appear). Thoughts - sorry, I know this a very complex topic.

Add -so I just went to open another file. Profile Mismatch dialog box comes up. It's embedded with sRGB. I am working in Adobe RGB.

do I use embedded, convert, or discard? (and why?)

I recommend letting me borrow your 300mm f/2.8 and having such nice glass in my hands will help me think deeper on this problem you're having.

Sounds like a gamut problem. It's possible that there's no 8-bit representation of the color you're after.

It's a start, - happy new year

LOL - yeah sure, it's -8F right now - you'll tell me it got frozen to the palms of your hands and I'll never see it again .

The odd thing is this file is old and it has always worked fine. The whole idea of saving the master file was so I could just swap the image some day with no hassles. It is all in 8bit so I don't think that is it but rather something to do with the color space it is in vs the one it using to save it for the web (presumably sRGB). Color management is a PITA.

Thanks for the thoughts! I got it to work, but I don't like the methodology it took to do it. One day I am going to want to do something and that work around is not going to cut. Maybe I'll post up on the Adobe forums. Cheers.

Louis,

I've seen that with images that aren't color managed; i.e. images that weren't created with an embedded profile. Attaching, embedding or converting them to a new color space will often shift colors.

Sometimes it's a browser issue. It's possible that none of the old images have profiles, but when you embed one in your edited file, it causes your color-managed browser to use the profile for that single image.

I'd try treating it as non-managed. You do want to save in the sRGB space but I wouldn't embed a profile.
