What is visible light?,
Visible light is the rays of 390 nm and 780 nm wavelength, which occupies a very small place in the light spectrum. Blue light is the radiations of wavelengths between 390 nm and 470 nm. Color temperatures above 5000 K are cool colors ie bluish Lower color temperatures (2700-3000 K) are called "warm colors" (yellowish colors). As the wavelength of the light decreases, the color of the light starts to turn blue / purple and the Kelvin (K) value increases. ,

What is the color temperature, Kelvin (K)?
