I am 99% sure “Champagne Bronze” is a match to the Kohler Vibrant Brushed Bronze. I ran into a Houzz article a little while ago which showed the similarities. More on reddit.com

I have found that the descriptions of finishes can be misleading. I have seen antique brass, brushed brass, satin brass, champagne gold, brushed gold, antique gold ad Infinitum. And the pictures online don’t show the true colors. There are so many gradations! When you go see them in person and hold them next to each other, then you’ll know. I considered brushed bronze too but when I looked at them in person, most were darker than I’d realized and it wasn’t the look I was after. Whatever you pick, just make sure you can find matching stuff - lighting fixtures, toilet pull, shower hinges, grab bars, towel hook, etc.. All my stuff was purchased and is now awaiting installation (mainly Kohler vibrant brushed brass moderne shower fixtures, faucet handles, 3-light fixture & a sapphire Madeli vanity with brushed gold hardware that is close enough, but not exact match to Kohler) and my polished porcelain marble look tile is now being installed on the walls. I think it will come out really nice but it was very frustrating dealing with the hardware matching, which is why I finally went with mostly the Kohler stuff, even though sone of the pieces were higher priced than if I could have found closer matches to the hardware colors/shades/styles. My next headache will be the hardware for my frameless shower doors to match up with the Kohler stuff. The brushed brass is absolutely the look I wanted but it sure would have been easier to go with black or brushed nickel! More on reddit.com

I tell people on new construction jobs that they should avoid it. They do it anyway. I always hear about how hard it is to clean up a year later. More on reddit.com

I have (went to a Kohler showroom) and I didn’t think they were a good match. That doesn’t mean you should rule it out - not everyone would mind the difference in shade. It wouldn’t have worked for me though - the gold finish looked too light for what I already had. All the fixtures in this bathroom will be in Kohler Vibrant Brushed Brass Moderne. I’d found a recessed gold framed medicine cabinet that I loved but the gold frame didn’t match so I went with a plainer (unframed) beveled one (both were Sofia brand) with an arched top for interest instead. I also bought a Kohler 3 light fixture in the matching brushed brass finish to install above the medicine chest. If my bathroom was bigger, maybe it wouldn’t have been as noticeable.
