My mother was born colorblind.  It was very difficult to get used to when I was younger.

I also have a bit of color vision deficiency, its not total for me, is it hard for her? Can she drive?

She could drive.  She did not see red or blue.  Green was awkward for her.  It seemed the brighter the color the less she could see it.
