Sorry, ORB = oil-rubbed bronze! :) Our backdoor hardware is oil-rubbed bronze, which I hated at the start of our remodel, but which actually looks more at home now that it's done--it plays off of the black fixtures, I think. (We also replaced the door with a stained rather than painted door, which helped a lot too--so rather than "random finishes," we have the nickel on the cabinets, the ORB on the stained door, the brass on the painted doors/windows, and the black on the lights and accents (stove grates are black here too). Plus I totally forgot about the stainless hood, so yeah, we are not sticklers for matching finishes! (We do also have an older house, though, which I think gives us a little more freedom for finishes to vary than a newer house where everything was matchy-matchy to start with--even our windows and doors with original hardware vary in that some of the hardware and hinges have been painted over and are now "white" and some of the hardware is still brass.) Our kitchen is not open to any room except our breakfast nook, so we did match the fixture finishes there. But I don't think we needed to do that, necessarily. I would wait on your dining room fixture till the kitchen is done and see how you feel about matching versus not at that point.

We have an open floor plan and are mixing antiqued bronze with brushed nickel. I was advised that it was fine to mix the two, but to not go MORE than two, if that makes sense. And the lighting consultant told me it was fine to do the aged bronze in the living and dining and switch to a more modern in the kitchen because you're defining it as its own space. Now I ended up going with Tiffany art glass in the kitchen, so the metal finish on the lighting was less of an issue. As I think of it, it is dark and keeps with that antiqued flow. I would have had no qualms going with brushed nickel if the fixtures I liked were in that. I did do a brushed nickel fixture in the laundry room (same wall color as the main area) and it looks really cute. For us, the brushed nickel picks up the brushed aluminum (same look) of the door knobs around the house. So like I said, we ended up with two metals and as long as I'm repeating one or the other, I'm not worried. As far as the cabinet knobs, well... For the hutch in the dining I used a satin nickel or pewter or something, I forget. The dining set is cherry and the kitchen perimeter cabs will be cherry, but I wanted to distinguish them. I think I'll probably do dark knobs in the kitchen. The island will be white/glazed, and I know I want to do dark knobs there. I think it would even be fine to mix them up, doing nickel on the perimeter and antiqued on the island. I'm probably not going to do that though because I have some decorative knobs (sentimental value) that I'm going to bring in. I'll probaby just keep it simple and do all antiqued and be done with it. Our stove is stainless with black top and the other appliances black. I figure the stainless stove repeats that silvery nickel color found around the house. So I say you can mix it up, but make sure you are REPEATING something enough that it looks intentional, not isolated. The other thing I read is that if you're going to mix contemporary and antique, to mix them in equal doses. I think if you do an ENTIRE space with all matching fixtures and exactly the same, that could get pretty heavy. Ours is ok, but only because the art glass breaks it up. If we had done all matching fixtures over the kitchen, living and dining, that would have been too matchy-matchy, not very interesting. I'd definitely feel free to break it up with some color or another metal, so long as it's one that will be repeated in the space. Good luck! :)

Lovely kitchen in the making but that light fixture for over the table is just too too much. Will you need pendants over the island?

Yes, no one can look at both and take the time to be picky about it lol. You will be the ones who notice things more than anyone. And after the dust settles most of the time you wont even think about it anymore. Side note I dont think you need contrast on your cabinet pulls, a brushed brass would be really pretty with bronze..just a thought.
