Gray mantel to tie in with gray sectional, table , etc and off white walls, like the tile around the firebox.

I wonder if the OP is high or does not know punctuation, or both.

The pictures in the initial post resemble a reality show.

Thank you! I love that. My only question regards the exterior. Will it be off that the exterior has beige siding, navy shakes and brown brick?

Wow Jim Mat. I’m not high. Point out my punctuation errors, please. Enlighten me. I have three children and made poor paint color choices. Please go along your way and consider why you feel the need to make cheap and unhelpful posts when other reach out for assistance.

My vote, SW Agreeable Gray. It’s beautiful. Very neutral, no pink/purple or yellow undertones. It would look wonderful with your trim color. Check it out.

Thanks kimberkc. I checked it out and it is beautiful! I think it would work nicely, as well. Thank you for your comment!

Thank you Marylee H! I really like all of them. I think my next step will be to prime a wall and paint each one to see which I like best.

I would suggest you paint 2xcoats on boards rather than the walls. It gives you greater flexibility to move them into both sunlit & shadowed areas - as the difference in light quality in both can be impactful on how the colour renders in your space. Also there’s no chance of the shapes of the samples telegraphing through the final colour either. 🌈

Great! Thank you for the tip, Marylee H

I am in the process of having my entire house repainted - only have a few ceilings finished so far. I have looked at a lot of lighter gray/greige colors - specifically trying to avoid undertones. I think I’m using SW Repose Gray for entry/stairway/upstairs hallway - and some other rooms. I’m also going to use the next color up on the swatch card - I think it’s Mindful Gray in Dow stairs half bath and study. Just a thought. Really nice colors - had my paint boards up on dining room wall during holidays - had a TON of family over on Christmas Eve - almost everyone picked Repose Gray. I had Agreeable Gray on one of the boards - it is pretty also.

I love that you are not afraid of color! That is amazing. I have been using "Glimmer" by Sherwin-Williams. It has a tint of gray & white, so lovely neutral color. Have you considered wallpaper? That fireplace wall could be a great place to consider for that. Good luck! Continue to be Wildly, Wonderfully, You!

Happy New Year.

I wouldn’t be concerned about the exterior and the interior of your home coordinating. Good luck with your project!

dmac1108. Wow huge project! So glad you found a color that works for you and you love. The gray color we have is Repose Gray, and I do love it a lot! It is also in my sons room. My husband fell in love with the Kuka sectional we have, and I get that with the gray couch plus gray walls it was too much. Also after googling pain’t colors a whole bunch I read something about how you want your exterior and interior to be somewhat on the same page, and I over thought it and felt I needed to pick something that harmonizes and ties exterior and interior together. Thank you so much for weighing in, and I hope the painting goes smoothly for you all!!

I would suggest that you consider something between living in a Kaleidoscope and drowning in a sea of neutral.

With 3 kids it may also be easier if you had a bit more depth to the wall color than trying to keep up with white or nearly white walls.

Since you have the brown flooring and several different grays I would try something with a bit of green (think nature, weathered woods, rocks, branches, moss)

Here are 3 that I played with that will give you an idea of what I am going toward.
