Want to play decorator? Need color inspiration.

[halfpint]

I have a totally neutral blank slate to work with. 

My main floor is mostly open floor plan. The front door opens into a foyer/staircase, and a short hall that leads back to one long room - living room/dining/kitchen. There are some other closed off rooms, but from front door to the back of the house, I want a unified color palette.

We're finishing our basement, so that will be our family room/TV space. I want this main floor room to basically feel like one open entertaining area - a few more structured seating pieces on one end (will be buying new couch or love seat, and chairs), then a table that seats four, before it flows into the kitchen. 

I don't really have anything to start with, no art or anything. Walls are a very light beige, floors are a darker wood. Doors and baseboards are white, and light fixtures/doorknobs are oil-rubbed bronze. Kitchen cabinets are cherry, countertops are a black/white/gray granite. I have a couple of little French-inspired kitchen wall hangings that are shades of deep blue, I could pull that in somehow...I had an apartment kitchen that was very kitschy country-French, like a rural boulangerie, and they are remnants from that. 

The room gets a ton of light. I won't repaint at this point. I'm kind of loving teal/gray combinations right now, but I feel like they're VERY trendy (and it's what we have in our bedroom). We previously had lots of warm browns and reds and oranges in there, but almost felt too warm for such a bright room? If that makes sense? Like it needs more spring/summer colors rather than fall tones. 

I just put these in my office - www.target.com/p/threshold-farrah-fretwork-curtain-panel/-/A-14263746#prodSlot=medium_1_40&term=threshold+curtains 

I do have this chair I could use as an accent chair, but I'm just as happy to start from scratch:
