Hi, can you post photos of your samples?

Yes. I think it sounds lovely.

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.

It depends on the look you're trying to achieve. For a contemporary and streamline look, I would select Dulux natural white for the kitchen cabinetry. Or, if you want the kitchen to stand out, I would suggest to choose a contrasting colour with the walls. A great way is to select your material and colours would be to take your stone and wall colour sample into a paint trade centre or hardware store where you can put them against possible options. Another way, is to have the stone, natural white paint colour in your hands, put them alongside the Jarrah floor and possible options. I'm not familiar with your style, existing furniture or personality so I'm taking a stab in the dark - but because your benchtop material looks like a cool grey, I would suggest to also choose a cool grey (like Dulux Sky Painting) for your cabinetry. Best of luck!
