Look at the Crossville tile site which contains several porcelain tile examples and is available in most parts of the U.S. It is reasonably priced also. There are several other porcelain tile manufacturers also - a search function on porcelain tile will yield some ideas on this site. I know contributors on this forum have suggested several beautiful ones in the past. Your stone is beautiful and fairly busy. I'd tend to stay with something simple, rectified (smaller grout lines), and complimentary to one of the lighter colors in your granite. Someone mentioned to me somewhere that horizontal surfaces should blend or compliment well. Don't know if that is accurate or not, but it sounds good. Gorgeous stone!!

I looked at the manufacturer’s catalogue and Matte is for interior and Grip is for exterior. I just ordered from Hexagon. I put the amount in the cart at both Hexagon and Art Walk and it was the same for both so not sure about the sale. Sounds like Heather got half and half. I ordered the Matte for my kitchen. Hope that’s right

I went with red based white in breakfast room and red beige in kitchen. Sabbia now I realize leans slightly green. When I was picking grout the darker I went the more I leaned towards Mappei Walnut which is a little green leaning. Not red based. Now that I have gone with red based whites and beige I see that perhaps green based whites and beige might be better. Perhaps Carrington Beige by Benjamin Moore. I had dupes made at Sherwin Williams of Farrow and Ball Dimity and Jitney and the dupes didn’t turn out to match the Farrow & Ball samples I had painted. They were off. I will post some pictures. I think light slightly red based but not too red or light beige slightly red based are ok. But the darker, green based.

I call myself the "color police"! I had my colors done more than 20 years ago and I'm one of those nutty people who is a winter! I stick to my colors (for my clothes) all the time. Crisp, cool colors look best on my skin tone. I don't have the money to keep my color rules to most of my condo, but I do for my kitchen floor. I love a very light colored floor in the kitchen. For 22 years, I've had a bright white floor in my kitchen and it always looks great and clean. I see so many people on youtube and in other places making mistakes about color. Taupe is one of them. Taupe is a neutral for me. If you Google taupe, you will get a lot of different opinions on the color. A true taupe is a gray-brown. You can have a taupe in light, medium, or dark. Here are cool colors: bright white, ice cool pastels, black, gray, taupe, silver, royal blue, pine green, forest green, kelly green, purple, cool red. Warm colors: ivory, cream, off-white, warm red, tan, brown, olive green, golden yellow, gold, orange, peach. I think a room should be all cool colors or all warm.
