Hi I'd go the colour of the wall. I love a white kitchen :) If you're looking for a point of difference, however, you could add some colourful cook books in the corner. You could also add little door knobs along the top cabinets, if you want, too help break them up a bit. Although drastic, removing the cupboard doors above the fridge and filling with colourful cook books would also add a pop of colour. It would still be in keeping with your shaker style too. Although, I'm sure you've just spent a lot on those doors, lol. Anyway, I think you've done a great job. It's a hard space to work with, small and u shaped. I can now appreciate the difficulties in working with an odd shaped kitchen! It's hard to get symmetry, so it limits what you can do. I'm about to do a similar style kitchen and was wondering what colour you used on your cabinets? They look great :)

You need to remove link it's got your address on it.

What look are you hoping to achieve? When you say 'update' can you elaborate?This kitchen looks new. Compared to my old Barbie pink, laminate, falling apart beast, this is a dream! I personally would never paint a kitchen myself- especially not one like this. Lots of sharp edges means lots of future chips/scratches. If it is 2-pack poly you could get it resprayed. I can see scope to change the cabinet pulls, add a plant or 2 to the shelves, bigreaders suggestions about moulding are awesome. Even if you got a cabinet maker to pull out the open-shelves and replace them with a timber or timber-laminate as a contrast. All this would soften it and add personality. I can see your roller blind on the window- changing that to a roman blind with a pattern/texture/colour through it would add character too.

You need to decide by taking large swatches to your home. The sunlight into the area will help you decide. Different whites will give different colours in different rooms. Only you can decide which colour is right for your situation.
