Although it is likely that the original poster might have replaced whatever fixtures she selected, I would add that Delta is a high quality product and the sole reason to "upgrade" to Brizo would be aesthetics. If you can afford it without sacrificing other elements of your remodel, then why not as most people wouldn't be at this site asking questions if we didn't care about aesthetics passionately. When I remodeled I opted for "expensive" fixtures based on aesthetics (and of course functionality and quality) and haven't regretted it. On the other hand, prior to the remodel my kitchen sink was the ugliest standard cheap Moen faucet and it last for years without issues of any kind. Also when allocating money in terms of priorities some elements can not be changed easily and other elements are relatively easy to change. A kitchen faucet is easily changed whereas flooring or cabinets aren't.

If you think the California Faucet's matte white finish would be an improvement over the current bonnet cap and possibly blend, then I wouldn't hesitate to contact them and ask what it would cost to have them repaint one of the replacement bonnet cap pieces you received with their matte white. I'm not sure how they operate: if they do one-offs with their coatings or if you would need to wait for a production run of other matte white pieces. For example, with my kitchen renovation, I ordered some Belfer recessed light fixtures, and the manufacturing system involved powder coating per piece. Normally the turnaround time would have been a few weeks for that, as they sent pieces to the powder coating contractor only as they were ordered by customers, but the powder coating schedule had been slowed down by pandemic restrictions, so it took about 4 months for me to get them. That's why I mentioned sending one of the replacement bonnet caps you have so you can still use the faucet in case it takes a while for the coating. Brizo doesn't actually use powder coating to apply its finishes. Its process is more robust, but I wouldn't be surprised if California Finishes has a process that is less technical being a smaller company and with some of the finish flaking problems I have read about with them. The bonnet cap is likely to be more protected than other parts of the faucet, however, so as long as the plumber can get it replaced without damaging anything else, it might be worth a try to see what California Faucets could do for you. Another thing to keep in mind is that you've only had this faucet for a few months, and I've read so many reviews about Delta's and Brizo's touch technology faucets failing after a relatively short time that I might be hesitant to drop money into a custom paint of the bonnet cap. A popular product on some of the older Houzz posts, especially way back when people were posting under the website GardenWeb before it merged, was a third-party foot lever that turned a faucet on and off. People back then loved this! While I think products like that still exist, they have been largely made obsolete by built-in touch technologies. Just be aware that the faucet may not last as long as it would otherwise without the smart touch feature. Yes, Delta/Brizo will probably send a replacement part to fix it if it malfunctions, just as has already been mentioned in this thread, but at some point you may want to evaluate whether you would like to continue paying a plumber to repair a faucet on which you may or may not have been able to resolve the color discrepancy. My Brizo faucets have regular handles without touch features, a decision I made after reading touch technology reviews, and I have become adept at operating them with a thumb or pinky finger in order to minimize contact with wet hands. I also use a sponge to wipe down any water that gets around and on the faucets after each kitchen session. There may be no going backward for someone who has used and likes touch technology, but if you do need to make another kitchen faucet decision in the future, you may want to do more searching at that time to see whether the longevity of touch technology products has improved. Looking again at Jason Wu for Brizo products online, it seems to me that you can almost see that darker finish on the bonnet cap in the promo photos. I don't know if that's just shadow or if it is a paint defect in the prototypes. Whatever the case, it's a terminal aesthetic flaw in the faucet. I'm sure plenty of people have called in about this problem before. It is frustrating that Brizo hasn't taken steps to fix it since it's just that one piece on the faucet, apparently. I'm so sorry you are dealing with this. If you do find a solution, you might want to start a new post for "Jason Wu faucet color defect" here at Houzz with some photos to make it easier for other people with the same problem to find out what to do.

Good Evening, Thanks to DCS who originally posed the question (3 years) ago, I ended up taking a risk and purchased the SINKINGDOM Garbage Disposal SinkTop Air Switch Kit with Long Button, Brass Made Cover, Champagne Bronze from Amazon last month after I went down the Rabbit's Whole with a google search for the Northstar Decor Air switch in their Champagne Bronze Finished with lead me to Walmart who advertises the Northstar Decor Air Switch BUT I wasn't able to order the Champaign Bronze finish in particular. So, I crossed my fingers while I waited on the SINKINGDOM order from Amazon. Then, I did a comparison and went back to my Fabricator to schedule an appointment for two additional holes cut into my new pre-installed stone countertops. When the Fabricator arrived, we played around with the distance between my Delta Champaign Bronze Faucet and decided it would be best to try and space the two holes as far apart as possible (9" on both sides) of my faucet which was already centered in the middle of my (30" wide) oblong sink. As soon as the Fabricator left, I cleaned up and setup a dress rehearsal! I know the Champaign Bronze finishes aren't exactly the same but please let me know if you think the color/finish/tone of the Air Switch is worth some experimental touching up?

By the way, here are photos from a few months ago when I compared a bunch of plumbing fixture brands. Photo w tile samples & lots of hardware: (L-R) Kohler Vibrant Brushed Moderne Brass knob, Kohler Vibrant Brushed Bronze knob, Delta Champagne Bronze hook, Moen Brushed Gold handle, Kohler Vibrant Brushed Moderne Brass handle Photo w tile samples & two pieces of hardware: Kohler Vibrant Brushed Bronze knob, Kohler Vibrant Brushed Moderne Brass handle Photo of hand and two pieces: Brizo luxe gold on the key ring, Kohler Vibrant Brushed Bronze knob Photo of hand and three pieces: Brizo luxe gold on the key ring, Kohler Vibrant Brushed Bronze knob, California Faucets Satin Bronze Hope this helps someone! Also for what it’s worth, I initially thought Delta Champagne Bronze was a great match for Kohler, but when compared to the Brizo it felt really off. Kohler & Brizo match beautifully, though. You may be able to match Kohler & Delta.
