Color weakness is also known as partial color blindness. For example, some
people cannot distinguish red from green; both colors appear as a yellowish
brown, as shown on the slide.
$
It is said that between 5 and 10% of Caucasian males are red-green color
blind.
$
There is another form of color weakness, involving yellow and blue, but this
is more rare.
