Not for me
It doesnt work as the screenshots show. I dont have a color circle to look at. All it does is cast a light glow on the ceiling, like light coming in from another room. You cant tell when it gets bigger or smaller. I am not sure how it seems to work for others. It would seem to me their ceiling is extremely low since mine is normal height, no cathedrals or raised ceiling.
