If you were asked to name all colors that you know, how many can you ?
10, 15, 20, might be 25 maximum.
It is also possible that some of you are not even able to remember 10 colors. But your brain can distinguish 1 million colors .
Do you know how many colors your eyes can distinguish.
A normal human have 3 color receptor cells and can see one million colors.
Only some women ( 1 out of million ) are born with 4 color receptor cells in there eye and can see 100 million colors . A man can never have that ability.
This simply means that all the mobile phone/screens manufacturing companies are just playing with our brains by providing 6 millions of colors in their screens and charging more money for that where 99% of humans cannot even distinguish those additional 5 million colors .
