Are red and green the only colors you see while colorblind?

People who are colorblind do not only see red and green. Color blindness, also known as color vision deficiency, is a condition in which certain colors appear washed out, dull, or even completely absent.

The most common type of color blindness is red-green color blindness, which affects the ability to distinguish between red and green colors. However, there are other types of color blindness as well, including blue-yellow color blindness and total color blindness (monochromacy).

People with red-green color blindness may also have difficulty distinguishing between other colors that are similar to red and green, such as orange, brown, and yellow. In addition, they may also have difficulty seeing objects that are camouflaged by their surroundings, especially if the objects are red or green.
