"The spot appears dark because the eye does not respond to that frequency. It's an error on the part of the eye
As frequencies, hot and cold have a range. When that frequency is higher than "white hot" the light is no longer visible. But it make no sense to call it cooler just because we cannot see it and it's out of the infrared and visible bands."
