When making albums for black and white photos what other colors aside from black or white would look good as background?

I’m not an artist and clueless what other colors aside from black or white would make suitable background color for black and white photos.

I already made one album with all of the background in black and another one with either white or black backgrounds. Not too keen on using only white background and gray doesn’t seem to work for me either.

Would very much appreciate good suggestions of color schemes for background as I truly have no idea what else to do. Thank you.
