This affects both survival AND creative.

While messing around I noticed a weird thing that happened in the sky when you walked into a cave or dark place. As you go into darker areas, the sky will become darker as well. This is of course the opposite of what happens in real life.

What I expect to happen:
The sky either stays the same, or becomes brighter as you go into dark areas.
What actually happens:
The sky gets darker as you go into dark places:

Steps to reproduce:
1. find a cave.
2. keep your eye on the sky.
3. walk backwards into the darkness.
4. notice the sky gets darker.

As usual I made a demonstrative video for anyone confused about what I am talking about----> http://www.youtube.com/watch?v=IXotNBd0nQA
