Choose a color from the stone for that wall , there is nothing there stopping you from doing contemorary decor. I am not sure what you mean by the decor, all we have is a picture of a fireplace wall no idea of what furniture you have or anything else.

Thank you for response.. I don't have the furniture yet, I want to highlight the stone wall and get the furniture based on the wall color for the fireplace wall. Does painting the wall to grey will look bad for this stone ? I usually saw white/grey/blue going good. Since I have brown and grey in fire place stone not sure how to select the wall color and add accessories to mantle and stone wall..

Your current wall color looks gray. Is it not gray?

no , its beige not yellow beige may be that's why lighting caused it look gray I guess current wall color is city loft from Sherwin Williams SW 7631
