Good luck dear friend

The color is identified by the 'cone cell' in the human eye's retina.

There are three types of cone cells to distinguish colors. One is particularly sensitive to red light wavelengths, another to green light, and a third to blue light.

Cone cell distribution ratios for the 'red region', 'green and yellow region', and 'blue region' are generally composed of [40]: [20]: [1].

Due to the relatively small number of cells that detect blue, many users in this App review say blue identification is the hardest.
