I like the look of this brownish green color which reads as a neutral and looks good with your blue.

I centered the console and change some of the decor so the view from one room to the other flows a bit better.

It looks so pretty. Thank you for the inspiration. Do you have this paint colors name?

You’re welcome. Here’s a few other ideas.

Your house and my house get the same natural sunlight. I chose B.M. Revere Pewter and it works for the 4 different natural lights. It will be perfect with the floors.

Make sure you test any colors suggested ... BM Revere Pewter looked like battleship gray when I tested in my previous house. I ended up using BM Grant Beige, a nice greenish-khaki that goes well with woods and lots of colors.

My walls are Alabaster and trim is Pure White, both by Sherwin Williams, it works well as a neutral setting for blue.

You want your wall color to harmonize with your existing hard finishes as well as your decor. Based on the tones in your tile, rugs, and LVP flooring (plus the wood tones around your home) I'd suggest trying Pacer White, Natural Linen, maybe Egret White. They'll all look good with cobalt too.

Put a BIG sheet of white posterboard behind your wall color sample board, otherwise your eye will mainly be noticing the difference between your existing wall color and the new color - impossible to block that out! When what you really want is to see how the new color looks next to your existing stuff.
