So how does it work?
The human brain and eyes work together to see colours, which are all different wavelengths of light. Objects have colours because they reflect those particular wavelengths of light and absorb other wavelengths - for example a red car reflects red wavelengths and absorbs the remaining colours. These wavelengths of light then travel to the eye, which works using photoreceptor cells called rods and cones. There are 120 million rods which detect mainly black and white information, while there are up to seven million cones which identify different wavelengths of light roughly corresponding to red, green and blue. We see colour because the brain pieces together all of the information that the rods and cones collect, and it often fills in "missing" parts in order to interpret the world around us. These monochrome images appear to have colour because the brain is filling in the missing information. Around 8% of men and 1% of women have difficulties seeing some colours, commonly known as colour blindness, and therefore they may perceive these pictures differently.DISCLAIMER: The Views, Comments, Opinions, Contributions and Statements made by Readers and Contributors on this platform do not necessarily represent the views or policy of Multimedia Group Limited.
