I love those cabinets (but not in that color!). For inspiration on painting that brick, look at subway tiled kitchens. Squint and pretend they are painted bricks. See? Looks good! Are you sure they're fake brick? Not that it really matters. It looks like a neat place--congratulations! I had cabinets just like that in my first house, but they were avocado green. I painted them white. I've missed them ever since. My counter had an ivy patterned Formica, so I didn't have the counter worry you do. (Hey you have a matching bifold door, already painted white!) But they do in fact look great in white. So, if you're keeping the counter, and why not, what about using white on the upper cabinets and a totally different color on the base cabs? Like a deep yellow or blue or well, you get the idea. The brick/backsplash area would then be a nice accent color, maybe. Were you going to keep the brick bricky? It isn't bad, and it looks good with more colors than you think. It ought to look good with yellows and tans. Cabinets are hard to paint (but worth it). Get that color right the first time. The brick, if painted, can't ever be brick again. But walls are easy. Go ahead and be daring.

Those are old-school water hammer suppressor risers and have been linked to Legionaire's disease. Bacterial growth is most prominent in stagnant areas such as storage tanks and dead ends of piping.

Also, some lights are yellow-ish and some are referred to as “daytime lights.” Switching to daytime lights completely transformed our living room (for the better)

Despite having already invested in the barn door option, I agree with other posters that a swinging door is the best option. The barn door track will look unplanned and out of place floating out from the adjacent wall. Door swing clearances are understandable concerns, but I still think it would be a bigger issue to have the floating barn track. Reduce the opening size to a stand door size (36" if you are worried about wheelchair, 30" if not.)will help with the clearances. On the flip side, it's really easy to take down the barn door later and just patch a few holes if you regret the decision.
