The pink color does not really exist.

 
The pink color does not really exist. That is, of course he is, but only in our imagination, scientists say.

The problem is that a combination of red pink and purple two colors which are on opposite sides of the rainbow spectrum.
Pink can not exist in nature without having to not bend the rainbow colors to red and purple mixed, that is theoretically impossible.

Color - is the way our brain and vision, and when you look at the pink object, it actually did not see the pink wavelength of light. It appears pink because certain light wavelengths are reflected while others are absorbed by pigments being depressed.

Thus the pink is a reflective, rather than transmitting the color that people see, because the brain converts the light reflected from it.
In fact, pink should be called "negative green" color, since it is the impact from the residual white when we remove the green color.
