We have a small bathroom that we're choosing new paint colors for. I think it was originally built in the 70's. I'm thinking of trying to match the red tile color and either use it on just one wall as an accent or use it in the whole bathroom. What do you think? Just one wall or all?

If it helps this is a spare bathroom off a room we'll be using as a office. It's unlikely many guests will use this bathroom as there is another more modern bathroom in the main living area.
