I never like white grout in kitchnes too many chances for splashes discoloring the grout and even time has that effect. Why not choose a really plae gray from the counter to grout and please make sure all that lighting is LED 4000K or all your choices will have a yellow hue to deal with .

Thanks Patricia, the lighting is all new LED and gives a nice bright look (In person)

The gray is the lightest, palest gray I could come up with. It is slightly lighter in person, for some reason it appears a bit darker, more contrast in the photo. I do like the look of all white, but am concered that all white may "fall flat" here with all the other white choices. I also am not going for a farmhouse look here, so want to be sure it doesn't give off that. My style is more traditional/transitional. I want to go with something classic and also a grout that doesn't have a big impact.

I like the gray, adds interest and highlights the tile more.

I vote white, frost or white, I like Avalance.

remember, it's the tile, not the grout you want to see.

What color is your cabinet ? I wonder whether it goes with Black under cabinets

@Ar A My cabinets are Pure White, they won't have any black

@Lyn Nielson I am struggling with that... I Like the Frost or the White. The White blends in well with the tile. (A warmer white tile) The avalanche I think would show up too prominently, since it is a brigher white. I am definitely in between the White or Frost. The frost isn't too loud, but I am afraid my kitchen might be too bare without the contrast of the gray. What do you think? My original plan was to go with white all along, but now I am confused.

it will never be too bare

Once you move in, Life will add the color/contrast you are searching for.

Go with your gut.
