We had the amazing Spade + Archer do a workshop about staging/preparing your home for saleat Think Real Estate. One of the most helpful tips were their "perfect paint color" recommendations for neutrals. Check them out if you're wondering how you should paint your walls.
Cream: Navajo White
Light Grey: Revere Pewter
Beige: Shaker Beige
White: Super White
Exterior Greys: Chelsea Grey + Amherst Grey with trim: Sailcloth or China White
For cabinet painting:
Step 1: use a TSP wash

Step 3: apply 2 coats of semi-gloss paint
Note that I beleive strongly in a splash of color and am loving the color a client added to her kitchen called "Hummingbird" from Martha Stewart (planning to add to my own kitchen, in fact!).
