STYLETHREAD -- LET'S TALK SHOP!

It's easier to visualize with paint bucket.  I did the tan color between the yellows.  I'm really not to keen on those shade of yellows.  I sorta like the yellow on the left but maybe if it was lighter.

I help people pick out colors for the inside and outside of their homes all the time.  Of all those colors you've picked, the yellow in the middle will work best.  ***HOWEVER**** it's a little on the bright side, and I think you'll feel like you're living in a lemon drop if you use it all over.  Pick a yellow that isn't as "lemon" but that has a little more "banana" to it.  It will be warmer and less "hello, I'm f'ing yellow."

Personally, though, upon looking at your pillows and furniture, I'd do a green or that powder blue.  The best thing to do, and what I generally do, is to take one of your pillows, find a green or blue shade in it, and match it.  Or, if all the greens are too dark, match the dark shade and go back 2-3 steps on that card.  If you *still* don't like that shade, pick up other green cards and find a green in the same position as the lighter green on the first card.  Does that make sense????  Do the opposite for the blue if it's too light to your liking.

Green works well with blue and red and yellow.

If you are looking to do different colors on the walls you mentioned, don't worry about if they'll look good w/ red X-mas decorations.  Those are up a miniscule amount of time anyway.  Focus on what will look good w/ your more permanent accents.  You can do the darker shade of the wall color you choose behind the TV wall (example:  dark green behind, pale green everywhere else).  Then do the accent wall in the dining room any color you wish that will go with what you move in there.  I always try new stuff in the dining room.

miss mee's advice is good -- she is totally right about the yellows.  they will be way too yellow.  yellow is a really hard color to choose.  it often turns out way lemon droppy. 

i think an avocado/leaf green would look be good for the main color -- it would look great with all the brown you have in the rooms. three i have used and like very much are benjamin moore's pale avocado (like it sounds), dill pickle (darker and more green), and spring dust (along the same lines of pale avocado but a little more yellow/brown in it).  all three it would work with the red for the winter.  they are the kind of colors that are there as a color without being harsh or shocking -- just the right amount of neutrality to them.  i think they would all work with your pillows. 

then you could do a richer, deeper green for the accent walls.
