I want to paint an accent wall in my living room this shade of green, but?

I’m not sure what color to paint the other 3 walls? I’m afraid if I paint all the walls this color green it will be too much, so I thought an accent wall would be a safe way to go. Is that a bad idea? I’m going for a country style living room like the one in the picture. Any advice?
