Answer 1

Color blindness doesn't mean that one can't see the colors at all. Usually it means , you cannot differentiate between Red and Green or Blue and Black etc. A very easy test , easily available with opthalmologists can identify your problem set of colors. A book with full of colored pages having different figures in different colors helps in identifying the problem. Usually, some letter or number is written in a color different than the background colour. So, if you are color -blind to a particular set, that page will appear plain to you, while other people will see something in it.
What your husband is saying is a very rare happening termed as monochromatic vision.

Answer 2

Not the most scientific answer but I'll try.

Color-blindness is a condition where a person could not distinguish particular colors. The problem might be found in the person's eye or the optical nerves in the brain. The colors usually related with color-blindness are green and red. Which is why you have to declare that you are color blind while taking your driver's test.

Answer 3

The cones and rods that allow a person to distinguish color do not work correctly when you are color blind. Most people who are color blind are male. You are both right, it depends on the degree of color blindness. Some people cannot tell the difference between colors, some only see in black and white.

Answer 4

Technically, you are both right. True colorblindness means you can only detect black and white (dogs are known for this type of colorblindness), as there are no cones in the eye, only rods. Regular colorblindness means you can see two of the three primary light-colors (can see reds and blues, but not greens... reds and greens but not blues... etc). The colors you cannot identify are mistaken as a different color (ie red-green colorblindness sees green also as a more muted red). Mild colorblindness has difficulty distinguishing shades of colors (ie aqua and turquoise look identical, lemon yellow and goldenrod look identical)... this, IIRC, tends to be a matter of processing the info (or having not learned or remembering the difference), and not directly related to the eye.

Answer 5

Partial affects only some colors. Complete affects all colors and is very rare. Color blindness most commonly affects reds and greens. Less commonly greens and blues. You can check it out on the internet. There's lots of articles about it.

Answer 6

there are different color blindness some people only can see in black in white but others are just blind to some colors like red...meaning they see all the other colors like everyone else but certain colors.

Answer 7

Color blindness is of three types.

They see colors but becomes difficult to identify one from another especially when presented together.

Comple inability to identify colors called Achromatopsia is extremely rare condition.

Most common color blindness or deficiency is Red green deficiency. Becomes difficult to identify between red and green, people with this are not suitable to become doctors, pilots, train drivers.

Answer 8

Well for animals color blind means only seeing black and white. In humans it means unable to distinguish certain certain colors.

Answer 9

there are degrees. most people just can't distinguish certain colors, like you. some have advanced color blindness, like what your husband is describing. Some mix up colors (blue is green, green is red, etc). and some just can't see a certain color, but see the rest perfectly fine.
