I would definitely get a white toilet

toilet should match the sink. white!

White!!

White! :-)

Thanks! It's probably tough to tell from that pic and I don't actually have the vanity yet, but I know there is a cotton white and colonial white from toto. Thoughts on these two colors?

I just asked this question too!
Cotton white is similar to Kohler and most other brands, Colonial white is similar to American Standard.

Cotton white matches our Kohler tub

Toto sent us chips of both colors, if they still do that, you can get both and compare them to your sink.

from what i remember from when i was toilet shopping, colonial white has a gray undertone and cotton white is 'white' white... which would probably look better with your tile... i didn't see an actual colonial white toilet, but did look at the color sample chips.
