yep, stunning. I been drawing something similar for a while and it's awesome to see your ab fab results after your OP. I got interested in some ikea solid timber benchtops, not nearly as nice as yours, and thought I'd combo them with black cabinets, white stone and white walls (just a "what if" design). so I totally love your kitchen. it's great how well the tiles look now compared to when you first posted, they really excite me! and the lightshades against the black wall. and what's that dining area I see? that smoked glass table top with timber trestles and black chairs and that black and white rug? where you get those?! I want to see more! congratulations, it's hard not to gush! big ups to Mldesign too.

I've noticed a recent trend of the vertical color on the island matching the vertical color on the splashback. Liking that trend. So I would say go with the turquoise glass splash back color. Deepen it a little so the hue is closer to that of the floor. Cant tell from pic whether island cupboards are the same color as cupboards above the splashback. If they are, all the better. That then brings the turquoise/white combo forward into the room and gives some unity.

If you really don't like the red you could paint that strip of tiles silver or put a stainless steel utensil bar across there and for the wood under bench their are also some very good adhesive metallic print/embossed papers out there again in silver/ stainless look mat or shiny then you would just need to paint the wine rack in silver/ grey ;)

We recently did our main bathroom in vivid white - it's great for a bright kids bathroom but when we do our ensuite this year I won't be going vivid again. I find it too bright if you have lots of natural light and I want warmer and more soothing. So depends a bit on the space, the natural light and the feel you want overall. Not sure if that helps!
