Wait till the counters are in then get sample tiles to make sure you like it. After you get the tile for your project, make up a sample board of the tile you choose using double stick tape. Pick one or more grout colors that you might like, then mix up a small batch and grout the sample board(s). LET IT DRY (overnight, as it will lighten up). Then see if you like the color for your kitchen. We ended up picking the 5th color we tried. Good luck!

I have black and cream window treatments with a bourbon colored wood floor. What color should I paint walls

If we could see your furniture and your style, we could make better recommendations. The wide fireplace would be perfect with MCM or modern style. furnishings. But you may be more transitional or farmhouse or another style. You have the good fortune that you can place the 2 focal points, fireplace and TV, right side by side, with the TV over a low cabinet on the hearth. That makes good functional use of the hearth area, so you don't need to think about removing it. Floor matching would need to be attempted if you remove the hearth, so not easy.

There are two schools of thought on drapes in a room. Some people like to have them match the wall color or be just a shade or two darker or lighter, some people like a contrast. If you're able to buy ready made because they'll work with the size of your windows, then look to see what's available that you like. If you buy ready made they're usually returnable, so you can bring some home and try them. If you have them custom made you will have a lot more options. Just definitely a solid color because your bedding is the star. I would wait until the bed arrives so you have everything you need to be coordinating with. I don't know if you have ever done this before, but if you see a shade of blue paint you really like but it's too dark, you can ask the store to cut the tint in half. I also think the paint on your walls currently isn't a bad match, just too dark, so if you know what it is, you could try that cut in half.
