Hi elconno, Not sure if you are in USA but I would suggest two colors by Sherwin-Williams called Upward and Wallstreet. The pic doesn't do the colors justice but the dark one I would put only on the wall your fridge is on - that includes the little strip above the cabinets. This will make the fridge disappear a little and it will be a great wall for a piece of art with a lot of color - it will really pop! The lighter color will go well with any teal accents you want and brighten the space.

Could you provide some picture of what you have so far? From what you have described I would probably go with a warm grey or light brown to match the veins in your floor. Good luck!

Consider going with tone on tone textured tiles. Keep it classical. Sometimes you can introduce a slightly darker contrasting grout color to accentuate the tile shape or design. The new trend is moving away from the subway tile look, it might date the kitchen in a short period of time. I would select your back splash tile before selecting the paint color. Paint colors I always select last, it is what pulls everything together.

Do you have any pictures you can post? Actual names of the products/colours already chosen? That would help to ensure any advice is appropriate.
