I'm biased because I just finished painting my kitchen and hall this color but ... Eider white? It is a little warmer but also so pale you almost think it's white until you see it against white trim and ceiling. It does not read as beige or yellow at all to me. As to the cabinet color ... it all depends on your budget and if you like any of the woods that are available. I chose a stained wood because I like wood grain and wanted something super durable against dings and dents. Maybe see if they have any wood cabinets that are not overly red or warm, it looks like you really like gray so I'm guessing you like cool colors?

needs a littlle more attenyion than just the tile, heating and paint. Are you really lovin' that tub and tile surround???? One note of caution with the heated floor and tile installation. Lay down the heating material on the entire floor. Saving money by only heating a 'path' will result in uneven floor tile. Just a little uneven edge on a tile is a pain on a tiled floor. This is a bare feet nuisance easily avoided.

You really need to show us the entire space so we can see how much oak cabinetry you have, what your flooring is, and what your granite countertops look like close up. Standard advice is to choose kitchen wall paint that is the lightest of the background color of your countertops. Show us that. Show photos from all four corners by daylight and with artifical light. That's how to choose a color. Yes, sage green goes well with oak, but what opens up next to your kitchen? That matters a lot. Here's a link to a great Houzz article about colors that harmonize with wood. Below is Simple Cream by Benjamin Moore. https://www.houzz.com/magazine/11-terrific-paint-color-matches-for-wood-details-stsetivw-vs~9025200 --Maybe a very pale gray would look great (even though I personally don't love gray in a kitchen). Your light sources matter a lot.

I think I’m just wanting to be sure this paint color works with this color stain. I know this all has to work together but the flooring works with the paint and the flooring looks good with the cabinet. I guess my question is just do these two colors (paint and stain) work together?! I know paint comes last :) I hesitate to put too many photos of things on because they don’t really ever look like they do in person. If you only had to answer could they work together - do they :)
