1. The physics Hyper textbook - Colour

This reading source, a website is dedicated to physics and its laws and concepts. The information

gathered from here were some factual proven information from the discoveries of several

people over the years.

Colour is not an intrinsic property of any object but the function of the human vision

system. No objects have a colour but the perception of colour is the mere reflection of a

particular wavelength of light from the objects surface that corresponds to a colour. Though this

wavelength light is an objective reality, the perception of colour is a totally dependent on the

eye of the beholder. The physics part of the light and colour ends when the light radiation leaves

the surface of an object and from there begins the biology and physiology. The light radiation is

received by the human eyes from the iris and processed at the retina with the help of many optic

cells – rods and cones. Rods are present in millions and help identify light, shadow, shade and no

light or darkness condition. It is the cones which have the property of deciphering the

wavelength of light and help decoding the colour. This decoding information is further processed

in the brain and the after effect is the colour image of an object that we view. “A given wave of

light has the same frequency no matter who is viewing it, but the person perceiving the color will

call it a word appropriate to their culture”; this suggests that the processing of the information

from the rods and cones in the brain involves some psychology and neurocognition from

memory as well. Talking about wavelength, the light we see from the sun or the spectrum has a
