Color Blindness
Color blindness, also know as color vision defects, is the difficulty or inability to tell the difference between some shades of colors. Frustrations for those with color blindness include reading color-coded maps, buying clothing, and traffic lights.

What is red green color blindness mutation pattern?
what type of mutation is caused by red green color blindness?
What do the colors on a blind cane for?
Usually white with a red tip. Some have bright dayglo orange reflecting strips as well.
Why cant women be color blind?
Women can be colour blind.
Answer
I am a woman who is red--green colorblind. The trait is carried on the X chromosome. Males receive an X chromosome from their mother and a Y from their father. If the X carries the trait of colorblindness, the male will be colorblind. Females need to receive two defective X chromosomes to be colorblind, one from their father and one from their mother. If a women has only one defective X chromosome, she will be a carrier of the trait. My father was red-green colorblind and so was my mother's father, making my mother a carrier of the trait, although she is not colorblind herself. I have two sisters who are not colorblind, as they each received a non-defective X chromosome from my mother. I knew before my son was born that he would be red-green colorblind, as the X chromosome he received from me carried the trait.
Why there is cure for color blindness?
There have been some recent developments that indicate that it may be curable. Scientist have recently found gene therapy that cures colorblindness in monkeys.

Where was the first color discovered?
Isaac Newton contribution to our understanding of color:
Today understanding of light and color begins with Isaac Newton. Isaac Newton was born January 4, 1963 in Woolsthrope, Lincolnshire. He died March 31, 1727 in London. At this time, England hadn't adopted the Georgian Calendar (they didn't until 1752), so technically he was born on Christmas Day, December 25, 1642. He was born the same year in which Galileo had died. Newton was born prematurely, almost 15 weeks early and he was so small that he wasn't expected to live. He published a series of experiments that he did in 1674. He was the first to understand the rainbow; he used the white light with a prism resolving it into its component colors. Red, Orange, Yellow, Green, Blue, and Violet. In the late 1660's, Newton started to experiment with his "celebrated phenomenon of colors." At this point in history people thought that color was just a mixture of light and darkness, and that the prism colored the light. Hooke the proponent of the theory had a scale that went from brilliant red which was pure white light with the least amount of darkness added, to dull blue, the last step before black, which was the complete extinction of light by darkness Newton found out this theory was wrong.
He went up to his chamber and shut out all the light except a little tiny bit then he put the first prism in front of the white light and saw a rainbow spectrum appear 22ft. away on the far wall. This phenomenon had often been observed before, but it had always been related to latent color that was said to exist in the glass of the prism. Newton took this simple experiment a step further. He passed his miniature rainbow through a second prism; and instead of turning into all the colors of the rainbow again it stayed the same color.
His conclusion was revolutionary: Color is in the light, not in the glass, and the light people see as white is a mixture of all the colors of the visible spectrum. Newton discovered that light behaves a lot like waves, bending around objects, much as water flows around them. When light strikes a prism, the different waves of color are bent to different angles, which create the rainbow spectrum we see. Red light bends the least and violet light bends the most. Newton discovered this when he was only 22.
Can a color blind individuals appreciate art and beauty?
yes, i reckon a colour-blind individual can appreciate art and beauty. you are thinking about colour here. Someone who is colourblind can still see and appreciate a work of art, nature or whatever theyre looking at without knowing what colour(s) are on it.
How does the perception of color differ from person to person?
based on personal experiences and beliefs we create our perceptions on particular things, that is why they are differed. in essence your perception becomes your reality.

How can you define color blue to a blind person?
Describing blue to a blind person would be difficult unless they were not born blind. Having no knowledge of what colors look like, or objects for that matter, you could not pose the idea, "blue looks like the sky." or "blue is the color of the ocean." unless the blind person has seen the sky or ocean before.
...But maybe they could understand that blue is the color of raindrops that fall on your skin.
What part of the eye does not work correctly if you are color blind?
There are two kinds of light receptor in the retina of the human eye. The rod cells work in dim light and do not distinguish colors. The cone cells operate in ordinary light conditions and they distinguish colors. My mnemonic trick to keep the rods and cones straight is to think of several cones of ice cream, naturally of many different colors. Color blindness has to do with the various processes of light perception by the cone cells. But color blindness is a more complex condition than you might think.
Can color blindness be treated or cured?
There is no cure for color blindness at present. There are colored lenses that can be used to help distinguish certain colors, but they are impractical for daily use.
Some researchers at the University of Washington were able to cure red-green colorblindness in monkeys using gene therapy, but it will be a while until such treatments will be ready for humans.
Is a color blind person disabled?
No, but it can put limits on jobs they can pursue - obviously they cannot work in fields where color identification is vital to performance.
Which colors does a color blind person have trouble seeing?
They don't... Blind people are enable to see any colour of any kind. (If they're fully blind). Do you mCean what they think about what colours might look like?
Color blind people do not see the actual color and will see only black, white, or grey.
What is different about the eyes of a color blind person?
If your color blindness is genetic (as opposed to having been caused by trauma or neurological issues), the only part of the eye 'affected' would be the cones, that part of the eye responsible for discerning color.
What causes some people eyes to have a lighter color?
smoking can contribute to the yellowing of the eyes also if you have hepatitis or are jaundice because of an underlying infection or disease this can also contribute to yellowing of the whites of the eyes hope this helps, Good Luck and God Bless!!!
When was red green color blindness discovered?
Extraordinary facts relating to the vision of colours, was the the first scientific paper written on this subject by John Dalton. He was the first recorded person in medical history with color blindness.
