People with a red-green weakness do not look the colors very similar. That means they have trouble keeping the two apart. (You see both colors as a beige gray)

Gives eye tests for color blindness.

Here e.g. a color gradation that you can recognize well normally.

People with red-green weakness know, however, that is red and green at the top of the traffic light. I don’t know how colour-blind people perceive their surroundings.

Rightly speaking, this is a color weakness.

A common error is that red-green blinds do not see red and green at all or as “grey”. It’s not like that. You can identify red objects as red and green objects as green. Only if both are standing next to each other, they cannot hold them apart and not say which of both the red and which is the green.

They also have problems with shades such as light green or dark red.

Even what you write is not really correct. There are many forms of red-green weakness. Most likely these people have problems when red and very bright and are not next to each other, but occur individually. Also red-green-weak people see the differences between the colors when they are visible directly next to each other, they can only not name which is. But as I said, there is not THE color weakness.

There is no color blindness. You have a color weakness.

Those affected by colour blindness only perceive their environment in grayscales and black-white. You got the difference now.
