Blue, cool color, belongs to the high-frequency light with the frequency of 600 ~ 700 Hz in electromagnetic visible light (equivalent to the wavelength of 500~430nm in the air).

Blue is one of the three primary colors and four psychological colors of light, representing the color of the sky. Because air molecules and dust in the air scatter sunlight in Rayleigh way (the scattering intensity is proportional to the fourth power of frequency), they scatter more high-frequency light (green, blue and purple light) than low-frequency light (red, orange and yellow light), so the clear sky is blue. Because seawater absorbs more low-frequency light (red, orange and yellow) than high-frequency light (green, blue and purple), seawater will appear blue.

The contrasting colors of blue are orange and yellow, and the adjacent colors are green and purple.

Blue is a symbol of eternity. Blue represents both melancholy and warmth and gentleness. There are many kinds of blue, and each blue represents a different meaning. In addition, there are many examples of music, books and movies named after blue. For example: blue, white and red trilogy.
