It's hard to say what it is without looking at it. Some cats have a darker pigment than others and instead of the nail bed being pink it can be black or a few shades lighter.
If her nail bed has always been pink and now you are noticing the change in color it could be a nail bed infection. Sometimes it has a smell to it and it will get crusty. An infection needs veterinary attention to clear it up.
Are all of her nails like that or just a couple? It's possible too that she might have bruised them if it was just a couple.
Just a few thoughts.
