Why is blue cold?

Can anyone explain this to me? Shouldn't red be cold?

Yes, blue has higher temperature, red has lower temperature. (For colors based on black body theory).
But culture associations are: red - hot, blue - cold.
And color T-s over 5000K are called cool colors, T-s - 2700-3000 - warm colors :smile:

because big chunks of ice have a vaguely bluish tinge, whereas fire is red. It's nothing to do with the EM spectrum.
