I actually really like having the white incorporated. I think it makes the white in the body of your fabric 'pop' a bit. Perhaps my monitor is a bit off but I think the tan/green make it quite monochromatic. Then again, if that is the look you are after - either of those would work. I like to find the least dominant color in my top and use a thin strip of either sashing/border to make that least visible color pop a bit just for some added interest.
But that's just me.
