D.Mohankumar Colour is the visual perception of different wavelengths of light such as red, green etc. Colour derives from the spectrum of visible light which interact with the colour sensitive cells of the retina to give the colour vision. Colour may be defined or quantified based on the degree by which the various colour sensitive cells are stimulated. The science of color is the Chromatics that includes the perception of colour, origin of colour in the materials and involvement of brain. Colorology is the science of colours and their impact on human beings.
Some Light physics
Light is a part of Electromagnetic radiation which is characterized by wavelength and intensity. Only a small portion of light is detectable by the human eye. This part is known as visible spectrum which includes wavelengths ranging from 390 nm and 750 nm. Below this range is invisible Ultravioletand above invisible Infrared. Visible light is a mixture (Polychromatic) of seven colours popularly known as VIBGYOR. Each colour (Monochromatic) has a particular wavelength. Of the seven colours, human spectral response is peak in the Green- Yellow region (550nm) because these colours are most abundant in nature. Yellow colour has more visibility than others so that is used in Sign boards, traffic signals etc. Even though only four colour sensitive cones are present in the human, eye different colours can be perceived through spectral combination of colours.
