call over and speak to Lindsey. She will send you out samples of any of the whites you want. tell her you have the carrara or email her a picture of it and she'll know what colors to send you.

(make sure if you order from them, that you ask about trim pieces. a lot of people are having troubles getting their trim pieces to match the actual tiles. )

someone else on here is doing Tusk and has some samples. I'll try and find it

I have a bunch of their samples, but in blue.

you could also do some silver colors.

Oh, look over at Encore Ceramics. they have some beautiful glazes you'll like. they have a ton of shapes and sizes too

Tilebar just got these. they have a soft blue that 's pretty, and a white

Seneca Tiles

Adding to what Beth has said, grab all the samples, but don't make a choice until the cabinets and counters are installed. Things can look a lot different once installed in your space.

I ordered a bunch of samples from Fireclay but they are delayed. I will look at Encore as well. Thank you both!
