It is not obvious in the picture that the two tiles don't go together. I can see the bullnose and field tile are different, but they don't look bad next to each other. Maybe it's the lighting in the picture? The shower stall is not well lit. This may be something you can only determine in person. Is the lighting installed yet so you can see it the way it will look when the room is completed? Do you have the vanity already, or a sample door so you can see if that will be a complementary white? Same with the countertop.

I doubt Greek Villa is going to work with what I see as it's probably going to be too yellow. But that is a minor problem - you can always find a different paint color. I would look for something that has at least a little bit of color to it instead of just white. You'll drive yourself crazy trying to find the right white, and then everything would be the same color which isn't very interesting. Lean blue, green or gray, depending on what you like.

Thank you for your input. its a new home build so i can make these other changes like wall color and countertops. I was also thinking greek villa might not be best color with my new beige and gray tile.
