I would let your natural elements shine ..match your wall colour to your classic white laminate and be lazy and paint the same for the ceilings so not to distract from your features or you could use your Caesar stone Urban as an inspiration and choose that colour as wall colour..ie go a bit lighter ..since you can play around with the colours as your room has lots of natural light .. Urban is a nice colour..brownish grey.. personally I'd just go white..

Plain ceiling white is a good choice for ceilings. I'm a huge Natural White fan but will consider Whisper White next time I'm painting.

You could have one side of galley kitchen cabinets in a richer shade of white (I'll have to start looking at the choices) and the opposite side in a grey. Will you have overheads too? Then the subway tiles in a softer shade of grey than the grey lower cabinets. I'd love to see photo of door handles.

Hi Steve, Did you have a question about which colours to use or a question about Duck Egg blue as an option you'd like to consider in your home? the info isn't clear. Please attach a photo so we can have s look at the rest of the colour and textures in the rooms.
