A soft, warm grey shade would look lovely, and can be as dark or light as you want. A warmer shade will work with the brown stained wood floor, and the grey will complement the black granite. You could have an undertone of green, blue or tan if you didn't want a pure grey. And it would look nice with any silver metal hardware, either polished or satin/brushed, so you could choose pewter, chrome or nickel. It would still work with white trim too.

this is looking good. finally someone on houzz has listened! Thank you. I would leave it as it is since any items you place up there needs to be maintained and that is one more task we would be adding to the lady of the houzz. but if you are still wanting to add something for that first client impression may be few large glass pickle jars or just two of three colourful glass sculptures. as would perhaps know - less is more in modern design.

'Pros' are that the finish looks sleek and seamless, especially when all the shutters are finished in the same colour. The 2 main 'cons' in the case of handle-less shutters is that 1. greasy finger marks can appear on the front face over a period of time. 2. there is a high probability of the user trying to pull at a shutter on the side where the hinge is. Handles allow the user to immediately see in which direction a shutter (or a pair of shutters) will open. If there are no handles, it is hard to tell and over a period of time the hinges could come loose. This is also the reason I don't fix the handles in the middle of the width. It was very fashionable to do that at one time, but it is just plain inconvenient

Priya, This is definitely NOT looking so odd that you have to change either the tiles/laminates. We understand your dilemma, it may be very diffcult to match colors of two different materials and finishes. To make you feel better, acrylics do fade a bit with use.. so eventually it might match as well :) As of now, you can add colors on the walls/ceiling/chimney remaining area. Get very good bold color handles. A kitchen rug,  dado mounted racks and colored accessories for taking away the attention. Stickers recommend above may be good options. Do try to make sure you have cutlery tray near the hob, not suggested to miss function over symmetrical looks. If the last section is a sink it is very close to electric panels.
