I think the two tone is fine if you like that look but I'd keep the fridge surround as white and panel the dishwasher.

Do you think that it could look good with wooden floors of a similar color to the cabinets?

Rule of thumb is keep the floor and cabinets a similar tone but two shades darker or lighter.

Another two tone option besides doing the uppers and lowers different colors would be doing one side (both upper and lower) wood and the other side all white.

Try Google image search with something like "two tone galley kitchen"

I love my two tone. I like stained wood but didn't want to feel surrounded by brown. I like things a bit mismatchy and seemed like a good fit in my older home. I did the tall cabinets white like the uppers so that everything at eye-level is the same color. Especially because the tall cabinets are right at the entrance to my kitchen (seemed like it would feel too "in-your-face" to have the wood there). I prefer two tone kitchens with the tall cabinets matched to the uppers rather than lowers, but I don't think it's terrible to match the lowers. You can find pics of kitchens done either way.

Agree to do a little contrast with the wood floor so it doesn't all blend with the lower cabinets. My kitchen floor was stained to match the rest of the house (IMO it's more red than I'd like, trying to tone it down with the rug), so I did lighter cabinets. I think it would be too much for the floor and cabinets to blend together.

I know what you mean about thinking that all wood would be too "in-your-face". We had initially planned on tall cabinets as a pantry but then decided that we wanted the light from the end of the kitchen to penetrate the room as much as possible.

I already feel sad that I don't have any seating in this room, but it is going to look out onto a deck and we live in CA, so I guess we'll get used to bouncing outside. And we do have a dining room, so there's that.

I've read in another thread where someone decided against two-tone because they thought one color would make the kitchen seem more spacious, and that may influence my decision. With a light enough wood, though, which would be necessary in order to adhere to DrB477's suggestion, it doesn't seem that it would create a closed feeling. My mom (a designer) is pushing for all white.

I don't know that I agree that one color makes the kitchen seem more spacious. I wonder if you had more accurate renderings if that could help you decide? I can't see the sink in the ones you posted, and if you decide to do a wood floor, that will change the look too. I think it's a really personal choice for what aesthetic you want.

My galley is 8 x 11, cabinets of quartersawn oak, stained chestnut on the lowers, with an off white stain on the uppers. My thinking was pretty much like caligirl5's and I think her last comment is on the mark, as well.
