SENSITIVITY

.


The graphic alongside presents
the luminosity function of the human eye.


We can see light in the turquoise-green-yellow portion of the spectrum much more easily  than we see it elsewhere in the spectrum.


Between 500 and 600 nanometers the human eye can 
differentiate about 7.5 million color shades.


Between 400 and 500 nanometers
the human eye can 
differentiate about  1.2 million color shades.


And between 600 and 700 nanometers 
1.3 million different color shades.

The average color sensitivity of the female eye is different than the average color sensitivity of manís eye.


Women have a better differentiating power concerning colors with high frequencies or low wavelengths than men. 
The colors dark violet and dark blue are the best examples. 
A black suit is seen as black by men while women are capable of describing the same suit as black with a hint of violet or blue.


The color sensitivity of the human eye
is for every person unique  ( just like a fingerprint )
changes according to the angle of view and
person's eyesight generally changes with age.
