No, it’s well known Raleigh scattering. Red and green have longer wavelengths than blue. Just past red, in the “wavelengths too long to be seen” direction is infrared which we feel as heat, and which just makes things warm. If you go the other direction into “wavelengths too short to be seen” direction, past violet, you get into Ultra Violet or UV, which is ionizing radiation, and that’s why UV is a skin cancer danger. The short wavelength blue light gets scattered, the longer wavelengths don’t, so the sky appears blue, and the sun appears yellow.
