What color should I paint my kitchen cabinets?

I've been in interior designer for 12 years now and when talking about kitchen renovation, the question I get most often is "What colour do I paint my kitchen cabinets?". 

​Painting kitchen cabinets is expensive and hard work, we don't want to have to do this every 5 years!

Here our client chose to go with the classic white kitchen cabinets, which is something I recommend often.
​White is classic and never goes out of style.  To amp things up a little, the island was painted in a soft gray colour, which works so well with the marble countertop.

Another great point about white cabinets, is that you can accessorize with whatever colour you are using in the adjoining rooms.  Above it's blue!   Below it's yellow!

What is your favourite colour to use when accessorizing your kitchen? I'd love to know!
