Most people believe that color blindness is similar to seeing in black and white like an Instagram filter or an older movie. That is not true, and in this case seeing in only black and white is a very rare case. For example, people who have been diagnosed with color blindness cannot see red, yellow or green.
“Color blindness is not ‘color blindness’! There are still a lot of people who think that if you are colorblind you really can’t see any colors. But the term is misleading, as more than 99% of all colorblind people can see colors. A better wording would be color vision deficiency, which describes this visual disorder more precisely” (www.color-blindness.com).
Preschool teachers, parents and even doctors could benefit from a little test booklet for the younger audience to discover color blindness at an early age. Not to mention also avoiding other visual issues in school because a lot of teachers depend on colors to teach their students. Someone who is not capable of seeing a select color may have trouble understanding the concept and not learning as quickly as the other kids do.
