What shade of yellow paint goes well with mocha brown color?

I'm looking for a yellow color interior paint that would look good with a mocha colored cast cement sandstone fireplace mantel and overmantel. There are a lot of shades of yellow so I thought I'd ask and maybe someone has some experience with these colors. I am painting the walls yellow but still not sure of what color to paint the ceiling so any help there would be greatly appreciated also. Thank You!
