Hi this is a big project question. We are doing our entire main level. We are updating our honey oak trim to white and using White Dove from BM. We are also changing our kitchen over to White dove from oak. We are changing our fireplace to move our TV over it and adding builtin cabinets similar to design picture added below. The backsplash and black granite will stay in the kitchen. All furniture is going...and I mean all including most nic/nacs.

First question:
In our formal living room that is now cluttered and red - see attached link to "before pix below" I want to do a very elegant, minimalist and sophisticated feel. WE are adding crown/case molding trim to the entry way to living room and dining room around the square area. I Love the idea of putting silver wallpaper design on that main back wall. The idea is four light colored/white/cream conversation chairs in here w/ small table w/ accents of metallic/silver and blush pink.
I love the wallpaper I have added below. BUT not sure what color would go with this style?? Would BM Glss Slipper go or Gray Owl be too dark?? I would also love to do BMoore Ocean AIr in here w/ no wallpaper - any ideas/suggestions.

SEcond question:
Paint colors. If you look at the zillow link below that has the "before" we are painting everything that is tan and dark chocolate brown. Keeping in mind our trim/blinds will change to white dove any ideas for colors. I am thinking Revere Pewter for the area that is chocolate brown now and the SW sea salt for the area that is tan as contrast into our kitchen. We are designing built in similar to attached photo below around the fireplace as well as area above fireplace for our TV. I am thinking of doing that back FP wall a darker contrast color - YOung Colt by BM suggested by a designer that came here but was SO RUDE and CONDESCENDING that I did not hire her even though we had the $$ to do so! I was shocked. Anyway.....I REALLY am struggling w/ this BIG Time. I LOVE the idea of a sophisticated light costal feel.
I was also thinking of Silvermist by SW for the TAN area or Pallidan Blue (?sp) but scared of the "blue".

Our kitchen cabs/trim will go White dove OR Marscopone - leaning White Dove.

I would just LOVE if anyone could help me or give me some advice! PLEASE PLEASE!

Here is what my house is like now - no haters please!
