are you really certain you want that horizontal mosaic with the granite in the first picture?

Pick a grout color that blends with the tile. It’s not that hard. But you might want to rethink your tile choice. You can always sell this on Craigslist. It is dark, and already looks dated, but if you love it, enjoy it.

Glass tile must be cut with a diamond blade. If your handyman doesn’t have one, don’t let him do the install.

Good luck!

I think it looks just fine as is. Are you getting rid of the short granite backsplash? Are you adding the mosaic tile on top of the granite backsplash or with it removed? I think it would look too busy either way. Even with the grout a matching color, which would be best, I really think it would look better if you did nothing. Money saved! If you bought the tile already, just return it. Sorry if this doesn’t help. :-(

Your tile has pinkish/purple undertones on my screen while your counter is yellow gold.

if that's true in real life than the colors could clash. Just my 2 cents

Sorry, but I have to agree with everyone else. I'm not feeling this tile at all. Everything is different shades of brown/tan. I would go with something much lighter & less busy. Pick out the lightest color in your granite & go with that.
