The number “12” is visible to all people, including those with any type of color blindness.

The number "15" appears to those with normal vision, a "17" to those with red-green deficiencies, and no number is visible to those with total color blindness.

The number "74" appears to those with normal vision, a number "21" to those with red-green deficiencies, and no number is visible to those with total color blindness.

What is Greener Than Green?
