Oh Bill, Bill.....trying to distract you again here. The grout colorant you mentioned says it can be used inside or outside...I think? Does that mean it would work for a problem with a "mortar" color on an exterior entryway? A portion of our flagstone topped landing coming in the front door of our house had to be torn out as it was not square. The mortar color of the part that was redone does not match the other part. We had a brown colorant mixed into the mortar for the entire project, but the redo came from a different bag and is darker. I don't know if there is a difference between "inside grout" and "outside mortar" as far as this colorant goes. Do you know? Thank you, Mr. Bill, for any help.

Wow - Houzz is right on those notifications when people post to your threads! Anyhow, we used the Delorean gray - it doesn't match perfectly, but it's neutral enough to be fine and I don't even notice it anymore. I did have an issue with the power grout though - it didn't cure right -- months after it was applied, when it got wet, you could scoop it out of the grout joints with your finger (or in the case of the shower, it washed out of the joints and ran down the wall). We had to go back and forth with the company trying to figure out what to do -- they were helpful but tried to pin the blame on the tile guy not mixing it right, which of course the tile guy denied. Then they said it might have been a bad batch. Or too much pigment. They had no idea, basically. We came this close to ripping it all out and redoing it (which the company had implied they would pay for), but before going with that nuclear option, the company told us to just keep wetting it and letting it dry -- that that would restart the curing process. After several (and I mean several -- like 15+) good soakings and then letting it dry out for several days (meaning we couldn't use our bathroom for months), the grout finally cured and it's fine now. And it holds up well and hasn't gotten stained or moldy like our old regular grout. But the whole experience would leave me hesitant to use power grout in the future. It may have just been a fluke bad-batch kind of thing or it may have been that the tile guy didn't mix it right, but it left a bad taste in my mouth where power grout is concerned.

We recently used Laticrete light pewter with slightly off-white subway. It makes the pattern pop and look vintage, but could be too dark for you. You might mix a bag of light pewter and bright white and arrive at the shade in your picture. Pick a few colors you like, and just Google the brand and name, then tack on "with white subway tile." You will get a lot of pictures.

Pretty PLEASE... Advice on grout color really needed!!! I'm looking for a gray color grout to go with Clay Grafito porcelain tile from The Tile Shop. I like the look of this tile & grout:
