ELI5: do 100% blind people see any particular color even though they are blind? If so, what do they see and why?

More so if they do see any color, how and why can/do they see that color. If they see nothing then how would you explain how that would "look"  to a person who can see?

I have read an interesting article about this. You might know there are some animals that have some sort of compass in their bodies. This way they can always sense what destination they are migrating at. Asking a blind-at-birth person what they see is like a migrating bird asking a human what they sense if they can't feel where the magnetic north is. 

To put this in another way. Your field of vision stops at a certain point. If theres a mosquito buzzing around your ear you can not visibly see it. Is the mosquito in an area that is black to you? Someone who is born with only one working eye misses an entire area of vision. Is this part of vision black? No, his/her vision now consists of the part that he/she can see, like all of our visions are. 

Blind people don't see colour, blind people dont see black. Blind people simply can't experience "vision or colour" in the same way that you can't feel a magnetic force.
