I'm new to Lightroom 5. To learn I tried to take an existing photo and improve it in the Develop module. I exported the results but the color cast is different in every other JPG viewer and browser from what I see in Lightroom. Even after adding the export to the Lightroom library and opening it in Lightroom it continues to look like what I had Developed. Why is Lightroom rendering images with different colors than everything else? I'm guessing there's a gamut adjustment somewhere I need to disable but can't find. In the export settings I've tried both the sRGB and AdobeRGB (1998) colorspaces with the same results.
Here is the original, followed by the developed image export as seen in Lightroom (via screenshot), and then the same image viewed everywhere else:
