OH man... I have trouble picking out clothes sometimes because I'm color blind! Do you know anyone who is color blind?
No I don't. It is also known as color deficiency and is characterized as the decreased ability to see differences in color.
Yeah, sometimes I have trouble driving because I can't see the colors of the traffic lights!
Oh no. It can make some educatonal activities harder also.
Yes sometimes. I wouldn't want to do art in university. I decided a career in mathematics instead!
Good for you. The most common cause is an inherited fault in one or more of the three sets of color sensing cones in the eye.
