Didn't you recently post this with a dark gray wall?

BM Twilight Magenta

BM Bullseye Red

BM All-a-blaze

BM Starburst Orange

BM Deco Rose

BM Crocus

An artwork selection that was a bit more interesting might make the bathroom more interesting also.

Any color in the art works, just a personal preference. A Raspberry shade contains pink/red/orange and will pick up on these prominent colors in the art, so could be quite complimentary

To make it a bit more fun, you could paint Cloud White in alcove behind sink (if you have some of your paint left - easy to try and if you don’t like, just repaint).

If you have a light in the ceiling, could update and sconces by mirror would be nice as well - brass is very complimentary with this color.

Tbh, I am loving your current color more than any other in the above-given suggestions!

These are great, it’s wonderful to be able to see another paint colour on the wall besides the green. All of them look so fresh and make you want to look at the art work. Yes I did post about a month ago, asking what everyone though of black or even white, the black could look great it might also end up looking drab. The area we live in is the Pacific Northwest and it rains for months on end and I think something a little more cheerful would be nice.

Love LOVE love your tulips!!

I also really like your present color ( and what is it?) but if you are feeling you need a bit more vibrant and cherry, I really like that Raspberry Pudding and the Crocus.

I love the raspberry pudding! I must confess that is my favorite color though! Now I'm just daydreaming what I can repaint! ;^)

I found these great towels

I’d also change towel rack and potentially...the faucet to compliment mirror (and lighting ideas in my previous post). Would be an eye popping bathroom.

I love the BM Eggplant that Jinx suggested. I think that purple and orange is a fabulous color combination for going bold in a powder room!

Maureen, thanks for the link for the towels the floral one with dragon fly. Who would of thought about checking out galleries to find towels to match artwork.

To everyone these colour choices are just what I’m looking for, today it has been raining all day dark and gloomy. I can see by changing the colour of this room when you walk by you will become energized.

Love all the suggestions.
What do you think of Cobalt blue or any blue, to make the colours pop or is to out there?

A dark blue would be lovely too, although not as vibrant as the other suggestions. My favorite dark blue is Benjamin Moore Summer Nights 777, which leans slightly green but is definitely blue and not teal. Cobalt blue is too harsh for me.

A blue with some grey in it could be a great way to add color to the walls while making sure the artwork is the center point of the room. Blues oftentimes show up more saturated on a wall than they look on a paint chip, so if you do decide to go this route, I would suggest getting samples from the paint supplier. You can paint them on white poster board and leave a little bit of the board unpainted so that you can see the 'true' color.

Although I can't know what a paint color will look like in your space without experiencing the lighting in person, Benjamin Moore's 'Summer Shower' could be a great starting point for you. You could sample it and if you're unhappy with it, Benjamin Moore employees are great at finding alternatives. (It's my favorite paint store, if you haven't guessed that already!)

Best of luck!
