Color blindness and color weakness are not the same, you must not be confused, the specific how to distinguish between the test, please see the following graphic introduction.

Please look at the picture below, the first time you see the picture, can you see what animal? If not, then unfortunately, you are color blind.

The test for color blindness is to keep taking pictures like this one, so that you can determine whether you are totally color blind or partially color blind.

Colorblindness is better than colorblindness in that it's not that you can't see the color, like in the picture below. A colorblind person knows that it's 12, but his reaction is slower than a normal person, and he needs to identify the color before he can be sure of what color it is.

The test for color weakness is to look at the picture below, you are not able to distinguish these colors, if you can't give the answer quickly, then you are likely to be color weak, of course, I personally recommend that you go to the hospital to check.

I hope this helps you, thank you!
