Simply White has a yellow tone. The tile has an orange tone. If you stick with colors with tones of yellow to orange, no matter how light or gray they are, they will work. 903 Pirates Cove Peach is a near match to the tile. I split the difference in tones between the tile and Simply White, then increased the saturation to get both 176 Goldtone and AF-305 Ylang Ylang from Benjamin Moore. Below is a photo showing all these colors on your wall. I cannot say that my color rendition is exact, nor can I say that your monitor will produce these colors the same way mine does. However, I found the color names for those I produced via an online program called Easy RGB.

I would just suggest painting the bricks another shade of white. The brick is already painted, and the cream color is really not doing anything for the space - and particularly since you are renting or selling, you might as well just paint the brick another shade of white. Doesn’t have to be a stark white. A warm white - but not a cream. You can look at BM’s Ballet White and Swiss Coffee as possibilities to sample. I like BM’s Natura Line. I wouldn’t go dark on fireplace, charcoal/black, etc. - because that is really more taste specific + it would be a very strong contrast with all the white walls and mantle. You are renting or selling, so best thing is to keep it simple, I think.

Home Depot is the only place within two hours that sells the pre-fab, and the colors are horrible. I need three bathroom countertops, and the largest is 52". I should be able to find remnants, but I can't even find fabricators who have remnants. Nobody has a website and the fabricators don't advertise, at all. I found six places in Tulsa, but none of them have quartzite remnants. I can only find stone suppliers. I will make a list of suppliers this weekend, and call them on Monday. Maybe they have a list of fabricators near me. Even Google maps didn't have anyone listed near me. They didn't have the two fabricators that are a half hour away from me. What is your opinion on glossy vs honed in a bathroom. My kitchen has leathered Sea Pearl quartzite, and I love it. I prefer matte colors usually, but I doubt I would like leathered bathroom countertops.

Since you seem to love this tile, what about trying to use a white caulk in the corners instead of the contrasting color. It may make the tiles look like they fold into the corner. You can try this before by just cutting some strips of paper and taping them up , then step back and see what you think. On a side note - was the floor tested for water? Those tiles are too big for a regular shower drain - it probably should have been a trench drain, unless there are diagonal cuts through the tile pitching them all to the drain ( can't tell in the picture ). Be careful moving forward - there seems to be some incorrect things happening here. Good luck!
