Colorblindness is a disability in the United States, but not in the UK and Canada. In the United States, colorblindness is considered a disability under the Americans with Disabilities Act (ADA), which means that employers are required to provide reasonable accommodations for employees who are colorblind.
Color blindness may be caused by disease, drugs, or brain injury (see acquired color blindness), but most often it is an inherited trait (congenital color blindness) that affects about 10% of men (it is rare in women).
Colorblindness will most likely be considered a disability under Americans with Disabilities Act (“ADA”). The ADA considers a condition to be a disability if it substantially limits a major life activity, such as seeing, learning, or working.

Color blindness occurs when there is a problem with the pigments in certain nerve cells of the eye that sense color. These cells are called cones. They are found in the light-sensitive layer of tissue at the back of the eye, called the retina.

Color Blindness Definition
Instead of seeing green and red as distinct colors, the person sees them as being very similar, thus the resulting color confusion and other frustrations.
The results showed that those experiencing SAD had reduced retinal sensitivity to light year round. Because colors are a reflection of different light wavelengths, it's possible that diminished light sensitivity in depressive conditions could impact color perception.
Abstract. Cortical colour blindness is caused by brain damage to the ventro-medial occipital and temporal lobes. A possible explanation is that the pathway responsible for transmitting information about wavelength and its subsequent elaboration as colour has been destroyed at the cortical level.
Tritanomaly is the rarest of all color blindness conditions, affecting well under 0.01% of both males and females. People who experience Tritanopia are lacking in blue cone cells. Blue appears identical to green and yellow is easily mixed up with violet or even dark grey.

Key points about color blindness
Color blindness happens when you can't tell the difference between certain colors in a normal way. And you don't see colors as most people do. This happens because of problems with special cells, called cones, found in the eye.
Females inherit one X chromosome from each parent; hence they can be either homozygous or heterozygous. A color-blind girl is born only when her father is color blind, and her mother is a carrier. If the maternal grandfather is color blind, the mother will be a carrier.
Thus, the correct answer is 'Her father and maternal grand father were colour blind. '
The first rule of making a palette for colorblind – avoid combining red and green. So if you're aiming to create a color blind-friendly palette try to use only two basic hues: blue and red (orange and yellow will also fit). The other colors should be made out of these two hues.
