I originally posted this on the Lightroom Forums and a user there (Beat) recommended that I should post this here. Here is my issue:
I decided to try and shoot some color optic fiber strands in pitch dark. These are early attempts, quite rough, and it's my first try at this kind of subject.
But as I was importing the RAW files in Lightroom, I noticed something not very cool. Whereas the photos seen on the camera have a varied color palette (blue, purple, even borderline red) the photo once imported in Lightroom looks uniformy blue.
Beat suggested that I should upload one of the RAWs, which I have done here: http://harmonica.typepad.com/IMG_1707.CR2
He also extracted a variety of jpegs that I'm reposting here with his comments.
Any help would be most welcome, since I'm kinda stuck on this one...

This seems indeed strange. Chosing the camera profile "Camera Standard" (first image) takes you a little closer to what the JPEG-Preview shows (second image), but the reds are still missing. "Adobe Standard" (third image) is actually the worst representation. I've also tried LR3, which pretty much shows the same effects.
If I were you, I would post this (including the link to the CR2) in the [url=http://forums.adobe.com/community/cameraraw?view=overview]Adobe Camera Raw Forum[/url], with a little luck Eric (an ACR developer) will have a look at it and give his (expert-) oppinion on the subject.
Try reducing chroma noise reduction.
I'm seeing the same thing as you, which suggests to me that the thumbnail jpeg is the odd man out. Not being a Canon shooter, I'm not sure of the jargon, but do you have a custom Picture Setting on this photo, which will produce a hue/saturation shift?
Camera Raw and Lightroom are unable to read the encrypted Canon data from your raw file, only being able to use pixel data and usually white-balance readings. Any other Canon-specific picture settings in your photos will be missed. Maybe if you use Canon's raw software (DPP?) it may tell you if the camera was setup far from default processing settings.
