Do you want to keep the "black falcon oven" as the feature or do you want the island to be the feature? If you want to keep the oven as the "feature" in the kitchen, then I would do the island in the same cupboards and benches as the rest of the kitchen. If you wanted the island to be a complimentary "feature" to the oven, then you could perhaps do the same cupboards, but go with a black benchtop (although I would personally avoid a black benchtop due to it easily showing dust, water spots, etc). What material will be "under-bench" be on the island bench? Is it also going to be a feature (e.g. a graphic print, timber or something else)? Will the island bench have waterfall ends? If the island bench already has some level of visual interest, then it may not need anything more (i.e. different materials). You can always add visual interest to the island bench with accessories.

I'd pick the cupboard white first. Pick what you love. Then get the wall colour tinted to match the cupboards. Nothing worse than mismatched whites. Either match them or go a contrast on the wall.

Hi Debbie Your new kitchen sounds lovely - a departure from average white!! A soft grey would be good, so long as it contained the blue tone you have chosen for the island. Would you consider a grey/green eucalyptus colour for the cabinets? Or a laminate that copies stainless steel? That would show as blue, to flatter the island colour. Have fun & let us know what you decide.

There are never right and wrong answers to this Cath....it can also become actually more confusing when you're not 100% and you get various/conflicting additional advice/opinions and then have to filter/distill the choices/options/opinions down to a final decision........when all else fails, trust your instinct/heart...you should "know" when it feels right....people sometimes ask why/how have I made a particular decision or move one way or the other, and sometimes my answer is simply "because it feels better that way than the other" - when it comes to design sometimes your "technical head" is your enemy ;)....sure the bench top material could look awesome as a splashback, but for you specifically the blue tile may be the better option, where it started and what you are drawn to......have you considered options such as a grey/earthy bench top? I've seen that done recently on a job (not mine btw) that combined with blue splashback tiles that you wouldn't expect to work on their own, but for what they were going for it was a perfect complimentary match.......when you get stuck with the decisions/palette resolution, sometimes freeing up and considering a lateral option is the answer to moving forward getting the balance and breathing space required
