Waterloo looks good in blue. Waterloo blue is close to stone wind blue, which is dark blue. Waterloo blue with navy blue is very festive. Blue is a cool color, which has a high frequency (second only to violet light) in the visible light of electromagnetic waves, and the frequency is 600 ~ 700 Hz (corresponding to the wavelength of 500 ~ 430 nanometers in the air), belonging to high-frequency light. 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 to some extent. 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.
