I don't know nothing about nothing but I would try and get some white ones and make a pattern with them to bring it together....maybe like this

but use white instead of black and maybe a little wider and use white grout?

Can't you exchange the tiles? I would pay the shipping/restock fee or sell them on craigslist if that's too high.

I think it will look OK. We have a bone/beige colored solid surface vanity countertop, white sink, white floor and shower tile and I like it. However, our walls are a really warm pink color and that kind of draws it together. I like the idea Sue had about adding some white tile. Or, how about a white tile decorative liner, or deco tiles?

It's not a mistake; it's a design feature. You meant to do it all along, right?

My fab new master has bone/crema marble-look porcelain tile and white toilet, sink, ceiling and paint trim. Granite countertop is caramel/bone/beige/mixed colors. Walls are soft green. It all looks lovely.

Just put other touches of bone and white mixed in with an accent color. Layer some beige and white hand towels in a basket...lots of ways to play up your new design feature!

Bone by itself is not not too bad but contrasted with white it looks dull and old. It will end up looking aged. Get white while you are still able to. Read the other threads where people ripped out backsplashes because the tile looked horribly dated against white cabinetry.

I agree with "Pharaoh". I think the Bone against pure white will not look that good.

I think it could work. It depends on whether there's enough contrast between the bone and the white.
