The Trichromatic Theory is the idea that there are three receptors in the retina of the eye that are each sensitive to their own specific color. These three colors are red, green, and blue. Each of these color-sensitive cone cells has different sensitivities, with blue cones being the most sensitive and red cones being the least. The combination of these three colors can form any visible color in the color spectrum.
If one of the three basic color mechanisms is absent or not functioning, it is called dichromacy. This is a mild form of colorblindness which predominantly affects males. This is because the mutated gene that determines colorblindness is found on the X chromosome. Being that males only have one X chromosome, if they have a mutant X chromosome, they will express the trait for colorblindness. Since females have two X chromosomes, they will not express the mutation if they have a normal and a mutated chromosome; this is because the normal X chromosome will be able to override the mutant X chromosome. Men do not have the additional X chromosome to override any mutations they may have on their one and only X chromosome.
This topic is particularly interesting to me because my best friend’s father has colorblindness. Her father wanted to be a pilot ever since he was a child, but was ineligible because of his inability to distinguish different colors. One day while her father was interviewing for the position as a helicopter pilot, he realized that his red/green colorblindness would prohibit him from obtaining his helicopter license. The reason he was not able to get his pilot’s license is because color distinction is extremely crucial when it comes to dash instruments and gun signaling on the tarmac. There are some circumstances when pilots are issued a license with restrictions. An example of such a restriction would be prohibiting flying at night. In all, colorblindness is mild vision problem that can greatly impact your daily life, but typically does not cause extreme complications or problems if you catch it early.
Young and Helmholtz gave the trichromatic theory of colour vision.
According to them, there are three kinds of receptors in the retina that are responsible for colour vision; One receptor is sensitive to the colour green, one to blue and one receptor is sensitive to the colour red.
These are also known as cones.
Their combined effect gives rise to colour vision.
