What is a nice beige color from Sherwin Williams to paint my walls?
The best thing to do is to go into the store and look at some paint chips. Hold them up next to other colors, because different colors of beige will have many different “undertones”–peach, brown, green, yellow, etc.–that might not be apparent when you look at the color by itself. Some paint stores sell sample amounts of paint that you can bring home and try on the walls before you buy several gallons. Have you considered other colors besides just beige? The right color (or combination of colors) can really liven up a room and add a lot of depth and interest to it.
