| What Marc says...
I will add some additional thoughts regarding colors in Lightroom. I suspect the differences you are seeing have to do with the color space used by Lightroom. The common color space in the Windows environment is sRBG. Lightroom displays its images using a color space with a wider color "gamut" called ProPhoto RGB. As a result there is often a shift in color rendition between Lightroom and other programs.
There is more to this subject as it relates to color profiles, exported JPEG and TIFF images and the programs that open them, but I don't have time to go into the details. It is enough to say that what you see may or may not be what someone else sees. I would suggest that you Goggle "Lightroom color space".
