We are thinking of installing black tiles and black grout for our shower floor and walls. Is it a good idea? Do they get easily stained with hard water?

Alternative is to go with beige or white tiles but I had hard time keeping the grout clean in the past with this color.

Any advice on whether black tiles is a better choice or not is greatly appreciated. I’m sure someone here must have installed black tiles for shower floor and walls. Feel free to add a picture.
