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

Your kitchen is a good size but not huge so I would go with gloss white to match in with your lovely fridge. All white appliances. Light coloured bench top in the grey range. Backsplash, I'd go to tile expo, choose something you love and add some colour behind the stove, the rest of the splashbacks behind the sink etc in white subway tiles. Dark floors as you have chosen, all the walls in the house Dulux Whisper White. This is a great colour to go with everything, i use it all the time in my designs.

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.

I assume the cabinets are laminate though -- it would be difficult to repaint them , PLUS a decent amount of colour will take the focus off them . The walls seem to have a blue tinge to them -- to me ,that adds to the colder , austere look . If I was going to repaint anything , I'd actually opt to do the walls in a warmer English Cream , or even a slight Apricot tinge would be more my taste . And then , the right hand wall in your 'new'pic 1 ( I think it heads to the rest of the house ? Theres a door there ) I would wallpaper in a textured paper , again with apricot tones ,maybe something like relatively simple apricot and cream diagonals 12-15mm wide on a woven textured paper ? ) . And 'double down'with the splashback tiles on the 'front' of the island . So that whole room would be English Cream or maybe a slight apricot tinge , instead of the slight steel blue tinge , with the warmer brown tiles , the pretty neutral floor , the slight coffee cabinets -- and then orange appliances and stools and pendent lights possibly . Obviously , you'd then need to go warmer tones for your dining furniture -- wooden frames , or black gloss and dark glass table , and creams , apricots , orange upholstery ? Mind you , once your present furniture is added , that may be enough ? It looks coldish and too neutral now IMO , but nice furniture will divert most of that attention .
