Color negative film can register much higher contrast than a JPG file or photographic paper. When you scan negative film, and especially with motives that have a high scene brightness ratio, the scanner post processing software will compress contrast to make it fit into 8 bit color space. As a result, the image will look faded and contrastless, just as if you print a b&w neg on gradation 0 paper. Get the negs printed optically and you'll see that colors are most likely fine and dandy. If you insist on hybrid work flow, plan for digital post processing on your computer.
PS: I realize that this topic reaches deeply into DPUG area. Reason I think it should still be discussed here on APUG is because many people judge color negatives based on poor and unprocessed scans and reach very wrong conclusions about the film material and its development.
