Worldwide approximately 8% of males and 0.5% of females have an inherited color vision disability. Normal color vision in humans uses all three types of cones in the eye correctly and is know as trichromancy. There are a variety of color vision anomalies including red-green, blue-yellow, as well total color blindness. Some of the most common types of red-green color blindness are simulated below, normal color vision is on the left of the pictures. For a more complete simulation see the vision demo link and We Are Colorblind website below.
Protanopia Type – Missing Red Cones
Deuteranopia Type – Missing green cones
Monochromacy – Very rare type, lacking color vision
