What are the colors?

1, blue

It is a member of the three primary colors of red, green, and blue light, and it has the shortest wavelength of the three primary colors, 440 to 475n nanometers, which is a short wavelength. The sky is blue on a clear day due to Rayleigh scattering of daylight by dust in the air. Due to the absorption of light at about 750 nanometers by the hydrogen-oxygen bonds in water molecules, a large amount of water is concentrated in a blue color.

2. Red

Can be mixed with blue (one of the three primary colors of light) to make a finished red, and can be mixed with yellow to make orange. The complementary color of red is cyan. Red is one of the three primary colors of light, it can and green, blue, mixed superimposed any color. Red, the color at the long-wave end of the visible spectrum that is used to excite an observer through energy, has a wavelength of about 610 to 750 nanometers.

3, orange electromagnetic waves in the visible light part of the long wave, wavelength of about 590 ~ 610nm. boundary between red and yellow color. Also known as orange or orange color. Orange is a cheerful and lively light color, is the warmest color in the warm color family.

4, green

is a color darker than the color of freshly grown grass or bright green, and in the spectrum of intermediary green and yellow between the kind of color. Green is the visible light part of the electromagnetic wave in the middle wavelength part of the wavelength of 492 to 577 nanometers.

5, purple (purple)

Purple is a combination of warm red and calm blue, is an excellent stimulating color. In the Chinese tradition, purple is a noble color, such as the Forbidden City in Beijing, also known as the "Forbidden City", also known as the "Purple East".
