If I had to guess, recent changes to the game seem have done something quite odd to the shaders that affect lighting in some areas.
(Note that I did not have this issue prior to the most recent patch)

What looks like it should be yellowish, or at least pale volumetric lighting is now just pink mist.

But for what it's worth, I can confirm this effect. My sister and I (playing on different computers) both saw this on our recent playthrough. I thought it was intended, though it seemed odd.
