It’s entirely situational. I recently painted part of our main level with a Behr color called “cotton grey” (using a different product) and we have multiple different lighting effects throughout the day. So far it has been great! It’s slightly warm, but has a very neutral ground. Good luck.

all paints have undertones and gray undertones are either green, blue or purple. a great resource is Kylie M Interiors. she has lots and lots of color videos that teach you about the different colors of gray and talks all about the undertones with the grays and what they will look like in North, South east and west facing rooms or with different wood tones. I always got her website if I have a question on a gray or white.

you pick a gray that is brown, black, or even yellow or red undertones.

Look at Passive, which has cooler green tones, next to Agreeable Gray which is in the taupe range. quite a diff. French gray leans more toward a neutral platinum gray

Anew Gray, Agreeable Gray, are warmer, brown/beige tone.

You can try a few of these

these two have a bit of red and yellow

also red undertones that give you more of a taupe shade of gray

Ben Moore Sea Salt has this perfect warmer gray tone

What isn’t explained by the majority of paint companies is that most every bkack/white/grey paint colour belongs to an identifiable Hue Family.

Sometimes that Hue can be discerned in the colour - sometimes not. Lighting quality plays a HUGE part in how we perceive a colour in our own space.

Passive is a chameleon. It actually belongs to the Green-Yellow Hue Family.

In balanced lighting many will read it as just a ‘light grey’.

In other situations more if its inherent ‘greenness ‘ maybe seen.

In lighting which spikes in blue-violet wavelengths it can appear positively blue!

This is colour shift. An effect of light quality and context. If it only happens at night, altering light bulbs will help. If it happens in the day, then moving Hue Families maybe the answer.

Evening Shadow is from the Blue Hue Family. It is a greyed-down, knocked-back blue.

You could try looking for greyed colours from different Hue Family neighbourhoods. See greyed colours from the Yellow Hue Family in the Colorography Lab at The Land of Colour to get you started.

You may have to reach back further back into the Yellow Hue Family to a colour like Classic Grey to help mitigate the blue colour shift.

Sweater Weather sits between the two.

You might find this beautiful room of interest.

SW Passive is on BOTH the window wall and the fireplace wall.

See how differently they render simply depending upon the quality of light to hit them?

I like both - I think they add atmosphere. But you wouldn’t want this effect to be a surprise.

Oh my gosh that is what we are seeing Though this is more dramatic!
