Your friend should tell you which stone yards he/she works with so you can go look at the slabs (with a cabinet door with you to hold up against them) and take home samples of the ones you like to see in your lighting. Given the warm tones in the cabinets and floor, creams or warmer whites would probably be better than cool/stark whites or grays. Unless you want to go dark - then a black would work well too. It all depends on what your style is, the colors you like, and what you are looking to achieve. Do some googling and searching on here - warm wood kitchens - and see what you like and strikes your fancy. While getting ideas from pictures is great to steer you in a general direction, slabs vary greatly in person so you MUST see everything in person or run the risk of being hugely disappointed in what you get vs. what you *thought* you were getting. https://www.google.com/search?q=oak+cabinets+with+granite&client=safari&hl=en-us&prmd=isvn&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjCyZLZ_eDfAhXIwlQKHd_jDnwQ_AUoAXoECAwQAQ&biw=375&bih=544

Don’t panic…I just finished a living/dining room with high ceilings and it came out so gorgeous. B.M. Mesquite. Looks wonderful with Hale Navy. Unfortunately the inspiration photo has used purple, but I hope you see the possibility.

I think the cabinets are beautiful, and the layout looks decent, though the stark white walls and ceiling do not compliment them at all. The backsplash doesn't seem to go well either (on my monitor). I would replace the ceiling light fixture, paint the walls and ceiling a warmer color, and live with it. As megs said, live with the kitchen for several months before making a major investment - if the layout just doesn't work for your family and lifestyle, and you want to redo the whole thing, you're farther ahead if you didn't spend $5K on painting the cabinets. There may be other things in your "new to you" house that take priority over a cosmetic change to a pretty kitchen.

There are scores of paint colors that will work with your wood floor, however you selection for wall paint will NOT work with your travertine fireplace. Select a wall color with less gold in it https://athoughtfulplaceblog.com/talking-about-paint-pale-oak/ https://www.remodelaholic.com/color-spotlight-benjamin-moore-pale-oak/
