Question 1

is there a type of color blindness where a person has trouble distinguishing shades of blue?

Accepted Answer

Yes: There are two situations in which the blue sensitive cones do not work properly  dichromacy is the most severe with complete loss of blue perception. 
Tritanopia (blue deficient: s cone absent)
anomalous trichromacy
tritanomaly (blue deficient: s cone defect)	
the most common color deficiency is red–green (overall)	7 to 10%	of the male population.

Question 2

if you have red-green color blindness, what colors in everyday life are difficult to distinguish?

Accepted Answer

Red and green: In red-green color blindness the patient is unable to distinguish between red and green.

Question 3

if a color blind person is red-green color blind, can they still see most shades of those colors normally?

Accepted Answer

Most: People (men mostly) with red-green colorblindness cannot distinguish browns from greens and oranges from reds.  Other colors, such as blues and yellows are perceived adequately.

Question 4

can you become a crop dusting pilot, if you're color blind?

Accepted Answer

Depends: Color-blind pilots are typically issued a restriction reading, "not valid for night flight or by color signal control." this mitigates the concern that color-blind pilots may not be able to identify those colors required for the performance of safe airman duties by preventing situations that are considered potentially unsafe. More info: wikipedia pilot certification.

Question 5

what makes a person color blind?

Accepted Answer

A genetic mutation: A person is born color blind because he has a mutation in the genes that are needed to see certain colors the way a normal person sees colors.  Most color blind people can see many colors, but the colors appear in a "different" hue, compared with how the colors appear to a normal person.  Very rarely does anyone have total color blindness and see only black, white, and gray.

Question 6

signs of child being color blind?

Accepted Answer

Depends upon age: Obviously inability to distinguish between red / green colors. Some have trouble with blue/yellow. It does assume the child knows his colors. I am not aware of a condition where no colors are seen. These are usually specific to certain colors.

Question 7

how can  someone become color blind?

Accepted Answer

Mostly genetic: By far the most common cause of color deficiency is a lack of 1 of 3 types of cones in the retina. This is inherited on the x chromosome. Which means it's most often passed on to sons from mothers. The mother's dad usually has the condition. Less common causes are medication toxicity and conditions affecting the retina or optic nerve, like ms + retinitis pigmentosa.

Question 8

how can i cope with being color blind?

Accepted Answer

Not to hard: Most colored things in our society will not be confused by the color blind.  You should not consider an occupation requiring good color vision like a fruit grader, or law enforcement. But most other things are open and many color deficient individuals do not even know they are color blind until tested.

Question 9

what do reverse color blind people see?

Accepted Answer

Color blindness: There is no such condition as "reverse color blindness."  the most common type of color "blindess"  typically occurs in males.  These people confuse red and green colors.  In rare cases, people can be born with complete color blindness and only see colors as various shades of light and dark.  In severe cases of color blindness, patients often don't see very well either.

Question 10

how to determine if someone is color blind?

Accepted Answer

Testing: The most common type of "color blindness" is red-green color deficiency. Blue-yellow deficiency or true color blindness (achromatopsia) are rare. Color testing can identify which. The problem is a lack of certain types of cones or their opsins (light-sensitive compounds). Red-green deficiency can be adapted to fairly easily and is not very limiting, but the others can significantly impact vision.
