Explanation:

this is all about the frequency and wavelength of a wave. Frequency is inversely proportional to wavelength. Red colour, which is closest to orange colour, has the maximum wavelength and this required least energy to travel long distances. Where as violet colour has the smaller wavelength with highest frequency, (talking only about the visible spectrum)

so during noon, the sun is so situated that the Rays coming from it are directly falling on the surface of the earth. This light doesn't have to travel a long distance to come to our eyes. thus the light is white as all the colours in the spectrum can reach at the same time to us. Where as in evenung, the sun is a bit farther away from our location. in this situation , light needs to travel a much more larger distance to come to our eyeS. Then those colours With small wavelemgth are unable to traverse that distance. Since red has the highest wavelength , it travels the while distance, but a few colours slightly reach our eyes as wheel like a yellow, this more of red Nd less of yellow gives rise to orange,

thats the reason for unbearable white scorching sun in the afternoons and pleasant and soothing evening red sunsets. As those waves with higher frequency cause damage to our eyes, since red has the least, it's soothing,
