              Color-blindness (color vision deficiency) is a condition in which a
              person cannot distinguish certain colors. Red/green color-blindness
              is the most common form of color vision deficiency. Red/green
              color-blindness does not mean those colors literally disappear. It
              means that some kinds of reds & greens (including some oranges,
              greenish-blues, and reddish-yellows) are difficult to distinguish.
