As you can see, we love Ben Moore colors! Here is a link that might be useful: great greys

You already have enough plants and organic things going on. You can either leave that space bare or find art of the same size as you currently have but with warmer colors to tie in with the wall color that can be seen of the upstairs area. You have so much gray going on (the trend for everything gray is definitely over) that you need some colorful accents for contrast and greater color complexity. Find some terracotta, gold or yellow pillows for the chairs and echo those colors in the painting.

would Alabaster walls with Pure White trim be decent combination for the main walls (living room, kitchen, laundry, etc) or would those wall colors be a decent choice or would those colors work well together Pure White works well with Alabaster. Neither one will make the other look dirty or dingy. I personally think Extra White is a prettier color of white but that's purely personal opinion. The color combo will be a lovely, flexible, neutral "envelope" for all the colors and contents you have planned.

Wandered over to Pottery Barn (not a fan, frankly, but they do enjoy their mix of grays and beiges...) And I think this is something that would look great. It's layering of both colors and textures... You could adjust the amounts to have more grays, but I think a natural linen would be a good starting point...
