Paint it a different color than the rest and celebrate diversity. Or hunt down one that does match-- I don't think most door companies have changed their designs over the last 35 years. Chances are if you can find the original maker they will still have the same door. Worst comes to worst a woodworker or good trim carpenter could make you one that matches exactly.

Me! Me! I hate FDs! A few years ago before the reno, I figured I'd get a fancy new FD fridge because if everyone had them they must be the bees knees. Then we moved into a neighborhood house when the reno began. My excitement over using the full-depth GE FD 36" fridge there quickly turned to loathing. I'm not a particularly wide person, but I found myself opening both doors every time I needed to retrieve or replace a item. Besides the ridiculous mystery of not knowing in which side of the fridge my desired item was, I just couldn't stand at the fridge with only a 16" view inside. Maybe I have some undiagnosed visual-spatial issue because I actually need to see the contents of the fridge when I open it. If I was just grabbing the milk out of the door, I would just open the right-hand door, but anything else meant opening two doors. And closing two doors. Seems like twice the work to me. I had the requisite landing space across the aisle from it, but I still hated the thing. Knowing I'd want to bash the life out of a FD fridge with a baseball bat if I had one in my new kitchen, knowing I hated SxS units for the narrow storage, and knowing I didn't want to be on my hands and knees digging in the produce drawers of a top freezer model like I've done for many years, that left me with a bottom freezer configuration. I scored a deal on a 36" BI KA from ebay. I smile at least once a day while at the fridge when I can open one door and see everything at once. The door is not heavy or awkward. I love my single door! Interior cu ft wasn't an issue for me as we've always had an extra fridge in the garage for overflow. I buy milk three gallons at a time, buy large watermelons in the summer, have a large weekly CSA share through the growing season, host all family holidays and entertain a lot. Even a large full-depth fridge in the house wouldn't be enough all the time. I find the bottom freezer easy enough to use. It's really not much digging with the factory organizational system of slide out baskets and drawer dividers. Again, a small freezer of any fridge wouldn't be enough freezer space so I have an upright in the garage for our large, organic and free-range pig and cow portions. Like A2, I wish I had the kitchen space for large, separate fridge and freezer units. Even though I don't understand the appeal of SxS or FD fridges, I'm glad people have various options. For me, even if a full-width fridge door blocked the aisle completely, and mine almost does, I'd choose it in a heartbeat over a half-door.

Totally up to you and what the room dictates. Brushed nickel is more popular these days and it really varies, as to what is right, from room to room.

I think it depends a little on what the panels on the doors look like. They could be shaker style, traditional, modern, or something else I haven't listed. They could be very rustic/cabiny! The style of the panels would guide my decision. If they're shaker style, I would look for some shaker trim designs. If they are traditional, with several grooves in the panels, I would consider something more elaborate. I hope that helps!
