In theory studio walls should always be painted black. however, in practice loads we see are white.
I guess you could have a go at painting it as near as you can get to 18% grey....then you could always use it as you would do a grey card to take exposures from?
If you need colours/ different backdrops for different effects, try Companies like Colorama or Lastolite. If you want a cheaper way of getting similar products those companies offer, why not try different linen and cloths for backdrops?
good luck
