I think how the cabinet color plays against the floor color will be very important. Does the Adel off-white look good against the tile? If it is reading tannish or beige-ish against the grayish white floor, then you might consider changing to medium or dark wood-tone cabinet doors instead. Since it's Ikea, you should be able to exchange them if they are still in the packaging. You would still have the white cabinet interiors but I don't see a problem with that. There is edgebanding tape if you need to cover any of the white box edges (I have a link around here somewhere). Speaking as a person who has white cabinets, white appliances, a light beige countertop and a light beige floor -- having everything be so light can get a bit bleak, even in a low-light kitchen. A bit of contrast will help tremendously. (I will be trying to add some natural materials and contrast when we redo, even though we will probably still have white cabinets.) As you see in the pictures below, good lighting is also very helpful, as well as good accessorizing. In my house we accessorize with stacks of mail and clutter. I don't recommend that. :) If all else fails and you still don't like your white tile, you could always add a nice big cheerful rug. Here are a few photos from House Beautiful: Better Homes & Gardens: Here are a couple with dark cabinets so you can see the contrast:

Thanks for all the great tips, everyone. My kitchen space is probably too small to carry off a black & white floor. Although, I do love the retro look. Another inspiration kitchen is oldhouse1's...I love the colors and this goes with my original intent of some kind of wood flooring. The yellow is BM's Windham Cream. I'd love to know what she used for the cabs. My dining & living area is adjacent so I'm wondering what colors would look good transitioning into the living area. How do you separate the colors?

Below are a few dining room ideas for your space. Please notice the tables, chairs, rugs, and various other decor.

Your kitchen is beautiful! The sample I took home looks to be a similar colour in my space. Thank you for sending pictures. What countertop did you go with? It looks like the ethereal line. We are currently between glow and Calacutta gold. Thanks!
