The second stage is the early period when pyramidal cells are forming, and it can only distinguish luminosity, and then begin to differentiate into two pyramidal cells which can identify yellow and blue. If there is no differentiation, it may be total color weakness. In the third stage, yellow vertebral begin to differentiate into red vertebral and green vertebral, if there has not this stage or has error in differentiation, it will cause red blind and green blind. If there has error in part section, result in the color which felt by vertebral is different from other people, which can lead to red weak or green weak.
