I think that black works just fine with nickel, in the same room and even more so in different rooms. It works with aged brass also. It is the overall color palette that can make or break a mixed metal combination.

You can totally mix metals, but photos of your spaces would be more helpful.

Edited to add photos to original post. We will also be changing paint from sherwin Williams Argos to truly taupe. Current paint and new sample photo attached. My goal is to create a cozier/warmer feel vs the current more light and airy feel.

That paint looks pretty gray next to your counter. If it were for me, I would prefer a creamier color to go with he gold and brown in the stone.

Taupes can sometimes tend to have a bit of a lavender or purplish gray cast. On my monitor, the Truly Taupe does (and SW also classifies it as a purple shade) and doesn't work with your counter at all, nor would it be "warm and cozy" to me. It may look quite different in real life, but be careful.

You have a great rug there - can you pull a warm wall color from it?

@BeverlyFLADeziner How did you paint my walls?! I definitely need to do this with some other colors! I hate my Argos walls though. Way too cool. Perfect Greige and mega Greige are also ones I’m considering. I feel like the more grey tones feel cooler and more beige is warmer, but want a Wall color that will go with both since I have a lot of deep gray decor.

@Zalco/bring back Sophie! any color you can recommend?

MB I use MS Paint that is on any Windows computer.

Some grays - even some deep grays - are warm while others are cool. You need to try to figure out which camp your deep grays are in. If they remind you of iron pipe they may be cool.

The paint company websites can be helpful too; some will let you search with a phrase like "neutral gray" or "Warm gray"

Thank you all!! So far from my original post and made me realize how clueless I am - ultimately I may end up hiring a designer to prevent a costly mistake! If anyone is Interested in helping more with paint colors let me know and I can send pictures of bathroom tiles and furniture! I picked out most things in my house before I realized the power of the wrong grey... however nursery furniture will eventually go away, so the master furniture and bathroom floor tile are the only things I’m afraid are “forcing” me into the Greige/greys.

You might be interested in the latest issue of Better Homes and Gardens - they have a feature of rooms done in mixed grays, blacks, whites, & brass that I found very attractive (surprisingly to me LOL). You might find some inspiration there for working with your deep grays.

@raee_gw zone 5b-6a Ohio thank you, I will check it out! I keep feeling like I made all the wrong choices when we built the house and the only way to get what I like is to start over from scratch

@BeverlyFLADeziner what do you think about SW Perfect Greige vs Mega Greige? Those are my two front runners of the Greiges.

Here are some greige colors that are a bit lighter and warmer.

Definitely check out https://samplize.com/ as Beverly recommended.

The paint samples are large & you can move them around during different times of the day to assess. I have SW Accessible Beige in my home & love it. From looking at your beautiful space, it may be a nice choice to consider. Good luck!

Well, @frostedsleet and @BeverlyFLADeziner... I had an interior designer come and look, and what do you know, she looked at all my paint samples, then went to her own bag of samples she brought and pulled out none other than Accessible Beige! I was SO hesitant/not onboard at all... and then the more I'e thought about it, the more I am so in love and feel like it is the right choice!!! And that just like I'd hoped, a designer saved me from a mistake.

One of my main goals in my home is to draw attention AWAY from the high ceilings and have a more cozy feel. I realized with a darker color, it's hard not to notice how much WALL there is and in turn draws attention TO the high ceilings. (I know many people love high ceilings... they're not my cup of tea but I thought I'd get used to them!).

So, about 99% certain this is what we'll go with and will probably order the peel and stick sample this weekend. The only thing I'm worried about is if it will take more paint/prep work and be significantly more expensive since I'll be coming from a slightly darker color, Sherwin Williams Argos. Any thoughts there?

A good quality primer coat, I think, will be enough. At least, I haven't had trouble covering a slightly darker color using good primer. The new formulas that combine primer with the paint might work but I've no experience with it for that. Perhaps a brand that offers a guarantee of coverage?

You might consider painting your high ceiling other than white - either the same as the walls (which I have done and like) or a different color altogether (which I have also done.) It is a great way to introduce a hint of color, and a certain feel, into a room without having it on the walls. For example, I have cottage white on the ceiling of my north facing family room - it counteracts the cooler feeling of the northern exposure (the walls are Simply White) as well as being a lighter, paler version of the Navajo White walls in the adjoining room - so it seems to flow with it. You can perhaps search for photos of rooms with colored ceilings.
