I think I've almost got a color narrowed down. I found a really nice grey that is almost right, so I'm going to try to get a darker sample and see if it will be as fantastic as I'm hoping it will be. However, I've hit another problem. As I look at my fireplace (which I hope to strip back down to its natural brick), I've realized that the proportions are really throwing me off. The mantle seems too small considering the size of the fireplace. Am I crazy in thinking so? Something has to be done with the mantle anyway, since it's not even attached to the fireplace. We can pull it right off, which seems a bit dangerous since there's also an outlet built into it. I like the look of this sort of fireplace, with the pretty white wood against the dark brick. They even have dark walls, which helps me to visualize what mine could look like. But given the shape of mine, I can't really see a way to achieve that look. Any ideas on how I might? The bits of brick that stick out at the top, as well as the fact that my brick doesn't extend to the ceiling, has me thinking I won't be able to just attach boards. Maybe I should just make the mantle a bit thicker? From the floor to the top of the brick is 52 3/4" and the width is 55 1/2", if that helps.

When it comes to transition areas, it's often a good idea to go with a neutral as they are more versatile. Transitional areas like entryway/hallways can have SO many colours going off of them, and choosing a 'colour' for this area, can limit you in other rooms. Personally, I would go for the soft, simple approach of Benjamin Moore Edgecomb Gray :). https://www.kylieminteriors.ca/colour-review-edgecomb-gray-benjamin-moore/  Also check out Benjamin Moore Stonington Gray which is GORGEOUS, but if this area is as low-light as it looks, you may want to lighten it by 25%! https://www.kylieminteriors.ca/paint-colour-review-benjamin-moore-stonington-gray-hc-170/ 

The tone of your cabinets is going to play a major role in choosing the right paint. Take a cabinet door with you to the paint store (not the home store) and ask for their color matching expert to help you pick exactly the right off white. Just buy sample pots of the colors you find and get some big white poster board. Paint a square or rectangle of color in the middle of each board. The white boarder will help keep your current paint color from distorting the sample. Move the boards around in different light, times of day and night and weather conditions to find the one that stays the way you want it to look all the time. When you go back to buy it, find a compatible white to do the ceilings that are looking rather dingy. The paint specialist will be your best friend.

I do not like that rug with that awesome tapestry or your sofa. IMO leave that out of the test. I also suggest you use poster board for the test not your walls , @ coats then move those boards around to make sure the color works everywhere and IMO all bulbs LED 4000K and I think really important to ge tthe lighting right .
