Have you ever wondered if another person is seeing the same color that you are seeing in a garment, household item or anything else?
Well, if so, you are probably interested in what We are going to tell you next.
How does the human eye interpret colors?
Let's start with the light , is a type of radiation whose wave has a length between 380 nm and 780 nm, meaning "nm" the nanometer, which is the unit of length equivalent to one billionth of 100 centimeters.
So, the radiations they are composed of cone cells and stick cells that are receptors of the energy that affect them and convert it into electrical impulses, which pass through the nervous system, reaching the brain in the form of codes and represented in c odors.This is a simple neurophysiological process.
Subjectivity in the appreciation of colors
According to the above, we define that an object has a certain color when reflects the Radiations Exactly at that hue.So that you understand better, a pen is blue when it absorbs all radiations except blue, which are reflected or allowed to pass through them.
Past this entree, let's go to the interesting thing, why does the human eye see an object of one color or another? As it is very simple, the sphere of 2 cm in diameter that is the eye is composed of the rod cells and cones that are specialists in detecting the size of the waves and collecting the different parts of the sunlight to turn them into impulses electrical , sent to the brain through the optic nerves, this organ being responsible for creating the color we see at that time.
How this process depends on ours and the eyes of each person, the wavelength can be measured exactly, but the determined color that the wave creates is subjective , so two people may be seeing colors differently and their interpretations may be as many as individual eye systems work.
It would also be necessary to differentiate between the process of producing colors by reflection of light on certain objects and the color appreciation of a computer screen, with direct mixing of light rays.You can expand information on the subject in « How are colors perceived? «.
With respect to cones cells, people have 3 different types in their retina, but there are exceptions in which, an individual can have an addition.If you want to know what a« tetrachromata «, check out this previous entry on our website.
