Blue: The Coolest Color on the Spectrum

Blue, the color of the sky and the sea, is a wavelength of light that our eyes perceive as cool and calming. It's the shortest wavelength of visible light, with a range of 450 to 495 nanometers. This coolness is not just a perception; it's a physical reality. Blue light is scattered more easily than other colors due to a phenomenon called Rayleigh scattering. This is why the sky appears blue - the blue light from the sun is scattered more than other colors as it passes through the Earth's atmosphere.
