Here are the issues I see: you want to modernize your furniture and make it more comfortable for all to sit in AND stylish as well. I also see from your picture that your kitchen appears to be a modern design so that helps with the whole "open" design. I would suggest you tear out the room divider that separates the family / dining room and make this one large space....make it feel more open. You will have to buy a new dining set to compliment your new family room furniture for consistency to your design space, especially in one very large room. You can keep the one chair with the floral print: just re-upholster this piece in a more contemporary print or a leather; I love to mix in some pieces like this with a contemporary sofa. Be careful in buying less expensive pieces like a sofa from some chain stores: they may look good but the insides are usually cheap and will wear out faster. Splurge on a good sofa....you will be happier in the long run with it. And with your family room larger now (with the wall divider out) you will need to purchase a larger area rug to go into your family room to make this room feel like its own room in the open space. And the vents that are in the wall divider can be moved. Good luck.

I love your rug. I had BM Shaker Beige with some navy (but it never did look black) which was very warm. Maybe give that a try?

Swatching colors side by side on the old color doesn't really help. You need need white poster board painted the colors you are looking at with a white edge around it. Then you move them around the room during different times of the day to see the color in the space. OR you can order from Samplize to try colors. I would try the Prussian Blue in your rooms as suggested. I think it is going to way to bright.

Any suggestions welcome for paint color ideas for color for my family room walls. The orange fireplace is throwing me off! Thank you!
