Although there are several forms of colour blindness, as Aaron Priven noted, the inability to distinguish red from green (red/green colour blindness, natch) is the most common condition. Probably around 5% of men in North America are red/green colour blind (compared to less than 1% of women).
What is color blindness? Color blindness means that you have trouble seeing red, green, or blue or a mix of these colors. It's rare that a person sees no color at all. Color blindness is also called a color vision problem. A color vision problem can change your life. It may make it harder to learn and read, and you may not be able to have certain careers. But children and adults with color vision problems can learn to make up for their problems seeing color. What causes color blindness? Most color vision problems are inherited and are present at birth. People usually have three types of cone cells in the eye.
