They can be such interesting creatures, very smart.
Part of your difficulty might be failing to recognize the color temperature of the light you're in. The human brain doesn't easily recognize differences in color temperature until there's a drastic shift. We automatically know that white is white and black is black. The camera doesn't, it's recording the actual scene. To me it looks like the room was lit by incandescent lights. Couple ways of handling that, first you can set your camera to Auto White Balance, shoot a test image of something white or preferably gray for color, then use the eye dropper tool in Lr to click on the test sample to adjust the WB, then sync all of your images to the same WB, or if your camera has adjustable settings for WB set it to incandescent. Here's a quick reference chart that might help you.
