I purchased a new dining room table, repainted my cabinets castle grey (Rustoleum), new counter tops, and purchased new furniture. I have an open floor plan and am having a really hard time picking colors to paint the rooms. I'm on month 4!! I have only chosen 1 color for an accent wall in the dining room, I'm not married to it though. I haven't picked out dining room chairs or lighting. I'm at the end of my rope!!! Can someone please help!! I'll add pictures of everything I purchased and pictures of the 1st floor

The sofa is creme
Chair deep navy blue with silver nail heads
Cambria quartz in whitney (counter tops)
