Question

Why does blue stand for cold and red stand for hot?

Answer 1

Blue suggests cool water or ice.

Red suggests fire.

Answer 2

Because of the heat radiation...

Heat radiation comes off in waves, like light,

and like light, there are different energy intensities.

Red is actually low,

Something that is at the highest temperature would theortically be white, or light light blue.

we generally are limited to are means of heat and we can only heat metals to red hot. if we could get em hotter, they would appeal different colors. Red is just the first one we see.

The red of fire and blue of cold, doesn't have to do with it.
