Blue is warmer than white

I only pay attention to physics and nature.  Physics and nature always get it right.  Physics also tells us that blue is warmer than white.  To illustrate this universal principle, let us look at the natural world, and the colours that animals have evolved in order to stay warm in harsh environments.

1.)  The Polar Bear

The polar bear is white, clearly illustrating its tropical origins.  The white prevents the bear from overheating by reflecting the harsh rays of the equatorial sun.

2.)  The Bird of Paradise

The warm blue colouration of this bird protects it from the icy waters of it's habitat in the icy waters of the Southern Ocean

Blue is warmer!  QED.
