Design Wide Walkways - "Paths throughout a kitchen should be at least 36 inches wide. Paths within the cooking zone should be 42 inches wide for a one-cook kitchen and 48 inches wide for a two-cook configuration. When planning, adjust kitchen islands and peninsulas accordingly." Grey with an undertone of green works perfectly with the green walls. Several greens can be put together without jarring the eye as long as care is taken with tonal differences. Notice the choice of white appliances!
