How do our eyes differentiate colours?

Answer 1

Your color has eyes from pigments, and genetics. Brown eyes are dominant, and blue eyes are recessive. So if you have a male with brown eyes, and a blue recessive gene, and a female with blue eyes, there's a 50/50 chance their kids will have blue eyes. If I, I have blue eyes, have kids with a boy who has blue eyes, all of our kids will have blue eyes, because between the two of us, there are no dominant brown eye genes.

yeah..dont think that answered their question...nice try though.

One thing I know for sure is that if two parents with blue eye's have kid's their kids could have blue eye's or a different color because another family member could have genes for a different eye color. Your gene's determine what color you eye's are.

Answer 2

The eyes "don't" see colour. The "brain" sees colour, the "eyes" are just "lenses", hun. k.

the eyes have two types of nerve cells. rhods and cones. Rhods help see in dim light and cones help in identifing colors and help see in bright light. these 2 cells are called photoreceptor cells. they carry this info from the eye through the optic nerve to the brain. the answer to your question, cones are nerve cells in the eye that help distinguish colors. :)

Answer 3

You have three types of cone cells in your retina. The one, which is stimulated by blue color. Another type of cone cells are stimulated by green color. The third type of cone cells are stimulated by red color. You can perceive thousands of colors by more or less stimulation of these three types of cone cells. So you have permutations and combinations in stimulation of these three types of cone cells.

In the back of the eye is a special neural tissue called the retina. Your retina has 2 types of photoreceptors, rods and cones, that capture light and converts it to a signal to the brain via the optic nerve. Color vision is determined largely by your cone photoreceptors. There are three types of cone photoreceptors: short, middle and long wavelength. Each cone type is more responsible for different wavelengths of visible light.

Roughly speaking, the short cones are responsible sensing violets and blues. The middle cones are responsible for greens and yellow. Lastly, the long wavelength cones pick up the orange and red colors. Depending on the intensity and the wavelength of light that hits your retinal cones, different cones will transmit signals to the brain. Two colors will actually look identical if the equal amount of photon absorption is done by each photoreceptor.

The color opponency theory suggests that there are three color vision channels. Each channel has two "opponent" colors. These three color channel opponents are Red-Green, Blue Yellow, and brightness. In this theory the channel of the brain for red-green works to see red but is opposed to green. So when your cone photoreceptors respond to red stimulus it will inhibit being stimulated by green.

Those who are born color blind usually are deficient in a certain type of cone (for instance being short on L or M cones). The majority of people who are color blind are males who have red-green color deficiency inherited from their mother. This is because red-green "color blindness" is an X-linked recessive gene. Because it is recessive, a female will only manifest color deficiency if she gets the gene from both parents since females have XX chromosomes as opposed to males who have XY chromosomes.

Answer 6

Eye color is based on the amount and type of pigments in the iris of the eye.

Answer 7

Light wavelengths vary and those variations are different colors (and spectrums).
