Actually the way they rate heat by color is quite interesting. Take a piece of 1/2 inch thick carbon steel, now take a torch and start applying heat to center in even circular motions to raise the temperature of the steel evenly so as as to not melt it. It will start to glow as temperature rises. The first color to be dectected by the human eye is Yellow, as the temp rises the glow transitions to orange then red, then green then blue and finally white. Then in the light bulb industry they will rate the light by kelvins and the color of the light will have a 2000 or 3000 or such kelvin rating corresponds to the color of the light that is given off by the glowing steel at that particular kelvin temperature. In such a rating black is O degree kelvin and therefore the coolest. What is more interesting in art blue is considered a cool shade and red is considered hot so they will call blue light cool white and red light is warm white and yellow called hot white, go figure art does not live up to science.P. S. If we forum members ever get a chance to all be in the same place at the same time I will give a test and expect all of you to pass with flying colors.
Wait wait wait red ones are fastest at getting police attention. black ones skirt by under the radar.
