I agree to go with a color with yellow undertones.

We just painted a color called "Latte" over the dark red walls in our place and we keep thinking that someone left the light on! It adds that much light to the place as the red was just sucking out any light in the place. Find a color you like more for that wall and repaint...and/or maybe add a ceramic tile backsplash? It will make it feel brighter in there immediately as you will get a lot of light reflection. I love the idea of sage green with your cabinets.

I love dark walls and I think your hall with the shiny floors and the right finish on the wall make it special. You already have the wrought iron, which definitely dictates a certain look. I hesitate to recommend a specific color from my monitor, but look at the BM colors in the 1037’s through the 1078’s and see if there is something there which looks good with the tile.
