Painting over cabinet doors can be tricky, depending on what material you're painting over. An easier alternative is just to replace the doors and drawers, and you can do this very cost-effectively by going for a plain melamine colour like this: If you have open cabinets instead of open shelves, it helps to keep the dust off but they still look great. Or you could go for wall cabinets either side like this:

I would stick with the natural white for cabinets... if your wanting white again.

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.

Hi Northstar, I had a bit of a stickybeak at your inspiration photos in your ideas photo albums - would that blue colour on those kitchen cabinets work for your laundry? With the timber countertops & white splashback? Although maybe it might be too dark depending on window light or artificial lighting, it could look really beautiful!
