Suggestions Needed...

I've been preoccupied this last week with a bathroom redo. Our half bath off our main floor living area has gone through a major overhaul.  Here's what it looked like last Monday. "Before photos" are always so revealing and embarrassing, don't you think? {That's a rhetorical question -- no need to answer and wholeheartedly agree.}

Because we loved the results of our master bath redo, we chose much of the same elements to use in this powder room redo.Within a few hours on the first day the room was gutted and it became a blank canvas -- ready to be repainted.

With two new coats of ceiling and wall paint, she was as good as new. I used white for the ceiling and Behr Ultra in "Plateau" for the walls. I love this "Plateau" color for the walls. It's such a great neutral color  -- so warm and inviting. The cabinetry was then installed, so the subflooring could be cut and the tile laid.

The marble tile came next. I chose a "brickwork" pattern for the layout -- so pretty with this particular tile.

Everything else was installed in less than a day...

This is where you come in... 
 I'm trying to decide what accent color(s) I want to bring into the room.

Below are a couple of up-close photos to give you a better idea of colors...

Any suggestions?
