From "Sherwin Williams Greek Villa: Undertones, LRV, & Real-Home Results"

"WHAT ARE GREEK VILLA’S UNDERTONES?

"Unless you have a TRUE white paint color, you’ll find undertones in any white you choose, it’s just a matter of choosing the undertone you and your home can live with! And because Greek Villa is a warm white, it has a yellow undertone...

"GREEK VILLA VS. SHERWIN WILLIAMS PURE WHITE

"These two are apples to apples as far as depth goes. With an LRV of 84, Greek Villa and Pure White are both soft, warm white paint colors. Where you see the difference is in temperature. While they’re both warm whites, Pure White is much less warm, with Greek Villa looking creamier in comparison. If you have one of the popular white quartz countertops, chances are it suits Pure White better than Greek Villa."

Wallpaper the space. You have a lot of tones in the room...tile, wood vanity, black and brass fixxtures. You need something to make the disparate look intentional.

Black frame pivot mirrors would look nice on a paper.

Or, something with texture, like this grasscloth (which can with stand humidity, properly installed, in bathroom with a good fan)

Turn vanity light to face down. You want bright, clear light right onto your face and the sink counter.

It will also reduce those shadows under your eyes, nose, mouth, neck. Have them on a dimmer, as well. As is, the lights are making the rough ceiling the star of the room. You don't want that, for sure.

If you are not interested in wallpaper, paint that area the dark of the wood vanity.

Any other siggestions? city loft looks oink. classix grey may work but is cooler
