Why: Apparently Daniel, Marcel, and Mischa are all at least partially colorblind.

Answer: First, there are several different types of colorblindness or "color vision deficiencies." 5 to 8% of men (1 out of 12) and 0.5% of women (1 out of 200) of the world are born colorblind. 99% of them are either protans or deutans.

Protanomaly (1 out of 100 males) is referred to as "red-weakness." Red, orange, yellow, and yellow-green appear shifted in hue toward green, and they appear paler and less saturated than they do to the normal observer.

Deuteranomaly (5/100 males) is called "green-weakness." Red, orange, yellow, and yellow-green appear shifted in hue toward red. Deuternomalous people do not have the loss of "brightness."

Dichromacy (2/100 males) is divided into 2 groups:

• Protanopia (1/100 males) - The brightness of red, orange, and yellow is much reduced. It can be so pronounced that the protanope may confuse reds with black or dark grey, and red traffic lights may appear to be extinguished. Violet, lavender, and purple are indistinguishable from blue because their reddish components are so dimmed.
• Deuteranopia (1/100 males) - Also involves hue discrimination problems, but without the abnormal dimming. The deuteranope may not be able to distinguish red, orange, yellow, or green.

The More You Know: Colorblindness is caused by certain cone cells misinterpreting the wavelengths that correspond to their respective colors.
