Well, not quite counter-physical: take iron and heat it, it will turn

Heat that red-hot iron even hotter, and you will eventually reach blue.
Every steel worker knows this.
and if you keep pumping the blower it might turn into some
sort of transparent plasma but I don't think most people are
able to heat iron that much not even to blue-hot, on the
other hand, every electrical stove will get red-hot on max power.
So it might be counter-physical but it is common sense that red
means hot and blue means cold.
