Kelvin Color Temperatures

Every since Thursdays class every time I see light I try to assign a Kelvin degree to it. Before our class on Thursday, I walked home at night and took to pictures of two lights that were shinning on a tree. Now looking at these picture after Thursdays class, I see that the cooler light in the right picture is more natural to the eye, then the picture on the left. As I've learned this is because the light in the right picture temperature is closer to the sun than the one on the left. Also the fact that our eyes are more use to cool light, which has a high color temperature while warm light as a lower color temperature. I'm guessing this also relates to color gel for instance, something like a R80. Does it have a high color temperature because all the of the other colors rays are being deflected and is this why a darker color burns out faster then a lighter one?
