For a project, I needed to submit images to a publisher in RGB. Photoshop, at least the CS5 version, uses a strange, home-brewed color profile called sRGB. The conversion to the correct color profile is described in this informative article, but then, when saving for the web as JPEG, Photoshop wants to convert the colors back to sRGB in the save dialog box (File > Save for Web and Devices > Convert to sRGB). Ensure this checkbox is not marked when saving the file, or your efforts might be for naught. Also, it's a good idea to check the box for "Embed color profile" for JPG file format when saving publication-quality files.
