I have white ceramic tile with a very very slight gray appearance to it throughout my home. I'm remodeling my master bath and have chosen a matte bright white porcelain tile with charcoal gray streaks through it, sort of like a marble effect, for the bathroom and the hall leading into the bath from the bedroom. I know now that I've goofed because the bright white next to the dull white ceramic is an eyesore. I've labored endlessly over maybe creating some kind of unique transition featuring a tile with gray and white mixed together to go between the two tiles but have not come up with anything. Please, I know there are oodles of creative people out there who can help me.
