Can males be tetrachromats?
Tetrachromacy is thought to be rare among human beings. Research shows that it’s more common in women than in men. A 2010 study suggests that nearly 12 percent of women may have this fourth color perception channel. Men aren’t as likely to be tetrachromats.

Evidence suggests that some people have four types of cones — including an additional orange one — and are able to see 100 million shades.

What does a strong protan see?
Strong protans struggle to see red, and colors containing red, and are often more acutely affected by their condition. People with strong protanomaly represent up to 10 percent of the estimated 300 million people worldwide with blindness.
Is color blindness a disability?
About Colorblindness/Color Deficiency Although considered only a minor disability, slightly fewer than 10% of all men suffer some form of colorblindness (also called color deficiency), so this audience is very widespread.
