I would personally stick to white cabinets... I know, not very original... but I think white works best with timber benchtops... and black/white/timber is a fail-proof/timesless combo imo... But if you wanted to inject a bit of colour... and based on your coastal theme description... then I would suggest maybe duck egg blue?... do a search of "duck egg blue kitchen" in photos on Houzz AU

I would paint all the brick everywhere warm white...satin for occasional cleaning. That done I think everything else will look OK because the colours are natural. New doorknobs are always good. You could if you wanted paint all the bench and cupboards white or rich cream as well....MUCH more spacious effect. there is a product you put on first and wait and paint...Hardware will knw...something like PSo

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.

Looking for advice of what the best dark colour (Matt finish) we could use for kitchen cabinets that would go well with a Black galaxy granite benchtop (black with bronze flakes through it). Thanks
