Here's an old tip but it's something I have to remind myself about every time I reinstall Lightroom: If you have Adobe Lightroom or Camera Raw, you can install additional camera profiles that will allow you to emulate the color modes from your camera (neutral, vivid, etc.).
I learned this tip from Mitchell Kanashkevich's Understanding Post-Processing (reviewed here) but I've also seen it been mentioned by Matt Kloskowski. Anyway, here's the link:
Just download the file and double-click to install. You'll then find new camera profiles available (under "Camera Calibration" in Lightroom). FYI this works only for raw and DNG files. Also be aware that the types of profiles that are available are camera-specific. For example, Nikon raw files will show D2X Mode 1, D2X Mode 2, etc. while Canon raw files will show Canon camera profiles.
