I have a Delta champagne kitchen faucet and it looks like bathroom faucet set you posted. It is a very light color, champagne is an appropriate description. The TP holder looks more brass.

It is possible their finishes don't match. Try to find reviews on Wayfair. A lot of people tend to post real life pics there and also comment on finish tones.

They won't be far enough off to EVER notice in a finished bath.

Online photography differences. And even your phone or monitor.

They have some variance. Which helps them to coordinate with other gold items. Because that finish NEVER matches anything outside Delta. Not lighting or cabinet pulls, or metal tile edging, or anything else.

The Delta Champagne Bronze is almost a light rose gold color - not brass at all. We just received our faucets/hardware today and it's not the gold/brass color we we hoping for.

The finish is in the name."Champagne"

If you want brass ?

Newport Brass

California Faucets

Brizo ( I think the finish is nicer than Delta )

Go to a good local plumbing supply - it's not a finish to select online, if you want brass.

I have multiple Champagne bronze items from Delta...kitchen faucets, bathroom faucets, toilet paper holder, shower fixtures, grab bars. There is no color variance in any of my pieces. The Delta finish is amazing--I had to have one faucet handle replaced and it matched perfectly. Unless something has shifted in the last five years, and I doubt it, you'll have no problem. The color itself is very true to it's name... champagne with just a hint of a red. It's closer to the faucet picture you have posted, rather than the toilet paper holder. I'll post a picture below...sorry for the calcification...I need to clean!
