Color Theory: Light
Visible light is the portion of the Electromagnetic Spectrum to which the human eye is most sensitive.
Isaac Newton discovered that visible light can be divided into colors.
Colors containing only one wavelength are called pure colors.
Pure colors cannot be divided into other colors.
The color of an object is determined by the wavelengths of light it reflects.
If an object reflects red light and absorbs all other wavelengths of light, it appears reddish; If an object reflects green light and absorbs all other wavelengths of light, it appears greenish; and so on.
