How beautiful!
Are these all precut tiles or are you cutting them?
You might want to consider the color of the stair landing before you choose, but I would think the "redder" the grout the better.
Looking forward to seeing the finished work.

I vote for pewter gray. That is very nice work!

What a beautiful medallion! I vote for the dark brown!

Very beautiful!!! I would go drk brown or black....I always go for darker colors though. Please keep us updated

I'm with Silvamae, pewter gray!

Thanks, all! I'm cutting all this tile myself, in my very masculine oversized coveralls in the driveway. I'm sure the neighbors think I'm nuts. LOL The small squares are about half an inch, to give you an idea of the proportion.

Funny you should mention pewter gray. Gray hadn't even occurred to me until last night when an artist friend suggested it. I'm in love with the idea! I think pewter gray with contrast nicely with all the tile but will not take attention away from the tile.

I just requested a grout sample chart online and then realized that it was an ordering site for architects. So we'll see if Laticrete follows through and sends the samples. I have some Delorean Gray from Home Depot that I'm thinking might work, but I'd love to see everything else that's available. I want to know my options.

Charcoal is my vote!!! Great job by the way!!!!

It's beautiful! Charcoal is my vote as well..

The medallion is beautiful!
I think the dark gray/charcoal would be great but many folks are much more creative with grout than I am.

That is beautiful, you must have alot of patience. I'm not sure of what color grout I'd go with but I do know I wouldn't use lime green!!!!
