I want to redo in yellow and grey but not sure which color for walls and which for cabinets

Hi Steff, since no one has yet commented, I'll start...we just bought an older 1974 condo & the cabinets are cheap wood, painted light blue a few years ago. Since we have a tight budget, we are going to remove the upper doors along the sink wall and use INSL-X Cabinet Coat paint in white as we, too, have white appliances. Our walls will be a light yellow (the backsplash tiles are yellow "daubs" on white). But I suggest you paint your cabinets grey and the walls yellow...lovely! We won't move in until the end of May, so I hope you post a photo of your completed kitchen.
