Sorry, I completely misunderstood your post. I thought you meant a transition piece between the two floors (ie, schluter, t strip molding). Don't grout that joint between the two floors. It needs to be caulked if you go that route. Otherwise, the difference in expansion/contraction between the two materials will cause the grout to crack. As far as grout color, look at lots of pictures. I would think you'd lose a lot of the beautiful herringbone pattern if you tried to match the dominant color. The tones of the two floors are very similar, so they already connect on that level. I don't think you have an issue of transitioning in terms of grout color. I guess the more natural selection for a wood look would be a little darker than the main color, like a shadow between the boards. A lighter color or a gray will look more like a tile floor with grout. I wouldn't do something lighter, as in peachy. You can kind of see what it would look like lighter right now. The higher the contrast you have with the tile will affect how busy or pronounced the floor pattern will look. Maybe you could cut strips of colored construction paper to lay over the joints to see what appeals to you more. You've got some variation in the tile colors, but when you use a grout color that matches the flooring, the floor becomes one big solid mass of color.

Thank you! This particular tile comes in 6" x 48" ... 8" x 48" .... and 6" x 24". I almost wanted to mix the three but was told that anywhere I used 8" would have to be. Full room-length run and so would stand out, and while adding a relatively few 24" might help with the randomness I want, the installers could also put too many together creating choppy looking areas that would also stand out. In one flooring shop I visited I saw a wood laminate that actually. Ones with varying lengths and widths IN THE SAME BOX! It looked awesome on the floor display, very real wood like. I wish tiles came that way.

absolutely , envelope via relief cuts, any size tile can be used w planning

French limestone in kitchen and wood in family room. Here they did an inlay with wood for sitting area and tile for the doors, around fireplace and kitchen. Do most people prefer one floor type? Sure, but there are exceptions and times when it makes sense for someone to do different floors. I am building and have a long back hallway that was supposed to be wood to match the rest of the house ... but this area will get lots of traffic and will be the area my 3 dogs stay in when we are out. I decided to switch to tile and it will work best for the way we will use the house. Some future mythical buyer can go ahead and rip it out at a later date!
