In the Reality TV show, Dancing on Ice, where celebrities are paired off with professional ice skaters and then compete to be ice dance champions, I've noticed the studio lights always match the colours of the skaters' outfits. It is quite clever actually.
I believe the changing lights represent the way the Universe is constantly mirroring our beliefs and expectations. The moment you have a change of thought, the lights change accordingly.
If I want my light to be consistent, then my beliefs and how I feel about myself have to be consistent.
I am being the Light I want to see in the world.
