wow! That looks great. I had trouble imagining how exactly it would look but I think this is darn close. Thank you!

Not a pro. According to the Sherwin Williams site, the coordinating colors with Accessible Beige are 7035 Aesthetic White, 7513 Sanderling and 9143 Cadet (a blue color). Out of the three the Aesthetic White is the lightest.

gold and gray and touches of black actually look quite chic together. If you were to pick a paint color with say, travertine flooring, I'd say "it doesn't go"..but as art and wall color together..to me, it works. Obviously agree with salonva-seeing more of the room will help to picture the space better thus give better suggestions for a new paint color if this one indeed feels wrong.

I would try for the lightest shade of blue. I hope you will be putting a glass door rather than a curtain so that you will be able to appreciate that tile. Side story: we just completed a master bath remodel and needed gray paint. All the popular ones from Sherwin Williams and Benjamin Moore clashed. We wound up taking a tile to Home Depot and it was scanned. They don’t really recommend this as a read on tile that has other colors through it as well as a hard surface, but we had nothing to lose. It worked!
