Understanding Colorblindness: Causes, Tests, and Solutions
TLDR Colorblindness is a condition that ranges from full color vision to complete colorblindness and is caused by the malfunctioning or absence of cones in the retina. Different tests are used to determine colorblindness in humans, and there are now software and design solutions available to help individuals with colorblindness.
Timestamped Summary
00:00
Color blindness is a condition that was first studied by John Dalton in 1794, who wrote a scientific paper on the topic after realizing that he and his brother were both colorblind.

Colorblindness, or color vision deficiency, is a condition that ranges from full color vision to complete colorblindness and is caused by the malfunctioning or absence of cones in the retina that are responsible for detecting color.
08:54
Dichromacy is a condition where a person has two functioning cones instead of three, resulting in a significant reduction in the number of colors they can see.

Animals, including dogs and cats, do see color, but not the full spectrum that humans see, and some animals, like birds, see more colors than we do.
17:33
Different tests, such as the Ishihara Plate and pseudo isochromatic plate, the anomalous scope test, and the Farnsworth Lantern test, are used to determine colorblindness in humans, with the FAA also requiring pilots to take these tests to ensure they are not colorblind.
22:02
Colorblindness is largely genetic, with red-green color blindness being sex-linked recessive and more common in Caucasian men, but it can also be caused by drugs and diseases, and acquired colorblindness is more likely to be yellow-blue colorblindness.
26:29
Gene therapy has been shown to work in monkeys for colorblindness, but it hasn't been tested in humans yet.
30:47
Colorblindness can affect various aspects of life, such as cooking steak, using crayons, and interpreting colors on electronic devices, but there are now software and design solutions available to help individuals with colorblindness.
35:09
Colorblindness was discriminated against in the past, but attitudes are changing and there is no scientific basis for such discrimination.
