You have a lot of things going on in here so here is my attempt to offer some advice: First, you need to change out the range to stainless steel to match the rest of the appliances. Your c-top choice for granite can work but you need to simplify the backsplash design (I suggest tile) to offset the movement in the granite. You might consider some under cabinet lighting to help highlight the backsplash and soften the look in there at different time periods. Once that is done, then look at your paint colors in there and possibly change up to compliment the new look and products (that off-yellow tends to make the cabinets look yellow/orange a little bit too and not sure if it will compliment your choice of granite?!) You're on the right path, just need to commit to the choices and then see it through. Good luck.

I prefer Quartz have you looked at it? That backsplash is too busy for Bordeaux granite.

I did look at quartz but like the movement Bordeaux granite has.

actually, to brighten up this dark and small feeling space, i'd look for a creamy base colored stone like khasmir gold or ivory gold, being sure to add an overhang on the island (if you like movement in the stone check out juprana granite) then exchange the pot rack over the island with either a pair of great pendants or a statement chandelier. from my own kitchen remodel experience i'll share you with you this: you'll get a much better price from a granite company then you will from a large home store ;) and be sure to take a cabinet door with you to shop. you can continue the granite onto the wall as a backsplash...they can cut the stone and make it go higher up the wall than the standard 3 inches which can be a great look. but if you really want tile, go for something simple that won't compete with the granite....like a cream colored subway tile. you can apply thim in a running brick pattern or a more modern stacked geometric pattern or even a herringbone. to control staining from food prep, don't use a white grout, use a slightly darker grout color that is inspired from the stone countertop. just remember that using a pattern on the countertop and another pattern on the backsplash can easily become overwhelming and then neither element stands out as the focal point. if you are spending a lot on a granite countertop, do everything you can to make it stand out as the best feature.

@ angusbreeder I also liked Durango beige tavertine as a backsplash.

@ potchiemagoodleberry : Thanks for the feedback and advise.

I really like it
