What color does an infinitely hot thing look like?

Color temperature is

a numerical value that indicates the temperature of thermodynamics called K (Kelvin) , and the color of light changes from orange to white to light blue as the temperature rises. Based on that, what kind of color will it be when you think of 'infinitely hot things'? The Azimuth Project, a research project on mathematical science, explains this consideration on the official blog.

When the metal is heated at high temperatures, it will appear to glow red or orange. Also, assuming a blackbody that absorbs light almost completely and does not reflect it, the wavelength of the light emitted by the blackbody will come out as a color at a certain temperature, and it will change from red to orange as the temperature rises. , Yellow and white, and when the temperature rises further, it changes from light blue to deep blue.

The spectrum analyzed for this light is said to be based on Rayleigh-Jeans' law. According to this law, the hotter the sunspot, the more accurate the approximate value, so the color of the 'infinitely hot sunspot' can be predicted. Also, according to this law, the brightness does not depend on the temperature, but the brightness changes depending on the temperature.

Furthermore, the appearance of color involves not only simple physics but also human perception. According to David Madore , a lecturer at the National Higher Telecommunications School in Paris, by elucidating the reaction of the human eye to Rayleigh-Jeans' law, it is assumed in the sRGB color space, which is also the standard in the Windows environment. It seems that it can show the color temperature of.

Based on the above, the 'color of infinitely hot things' is close to the following color shown in sRGB as (148,177,255). It is explained that this color is a typical neutron star color formed by a supernova explosion of a star, and is also the color of the early universe.
