I think that's going to be a lot more PURPLE on the wall that you're probably expecting. I do like the idea--just with a lot more gray. My husband is the opposite. He doesn't even notice colors. We once had a fight when I asked him to take something to the "blue bathroom" and he thought I was ridiculous to expect him to know which bathroom that was and that I was trying to pull some kind off fast one by referring to it as such. At the time we were in a 60s house with all original bathrooms. The whole bathrooms all had floor and wall tile (4x4 tile wainscoting to 4') that were one color with the walls above the tile and even ceiling painted the same color--because what a room with smurf blue everywhere needs is more blue. One was mint green, one smurf blue, and one was buttercup yellow. And the sinks, toilets, shower/tub were also the same color as the tile. Most memorable retort: "The walls are blue! The ceiling is blue! The toilet is blue! Even the toilet paper holder is blue! How can you not know that bathroom is blue???" Nope. Didn't know and couldn't believe that it was normal to remember something like that.

I just reread your post. Is the vanity coffee colored as in dark? If so, then scratch my previous post. If the vanity is dark, then you can look at BM Mayonnaise. That's a nice, warm white.

I really do love the turquoise tile. What would be a good color to paint above the tile? Maybe something in the medium taupe to medium grey? Maybe a color from that picture, which I like. Would love to get your favorite paint color choice.

it's not a film, I already checked. and I don't mean literally blue light. I mean cool toned. I find that window and glass vendors are not exactly educated in color theory. if you're color sensitive and truly worried, I'd seek out a lighting architect to help you figure it out. I wish I did. ultimately it boiled down to one major problem for me: the skylight was positioned on a part of the roof where it's deep in a shadow most of the time (a huge design mistake). shadows from sunlight tend to be cool toned. so on a sunny day when the shadow is strong, the light coming into the room is very weak and cool toned (like a dim 5,000K bulb). on a cloudy day, the light is diffused and better. thankfully this spring/summer/early fall, the shadows changed position and the skylights are actually very pretty. the reason why I started this thread was because I noticed the glass itself looks kind of blue-green and wondered if it was affecting the light quality. ultimately, I think the answer to that is not enough to make a difference. if your skylight or solatube is positioned properly, you shouldn't have that problem. I can be confusing when trying to describe things. hope this made sense!
