Question:

COLORS ARE AROUND US EVERYWHERE... 

We can see colors as a result of the interaction between light and matter. Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). The main source of light on Earth is the Sun.
