I think this relates.

In one of my recent lucids, just after I had read billybob's post about changing everything in a lucid dream. I found myself in my Grandparents house, and I morphed the house into a hotel(instead of teleporting), but the lights in the hotel were still the same color as they had been in my granparents house(yellowish for some odd reason) and I didnt like it, so I made the lights become white.

Not dealing with light intensity, but rather, color.
