When we moved into our house 2 years ago, the first thing we did was to start picking paint colours to warm up the stark builder-white walls. We picked different colours for pretty much every room. The order of rooms we painted is interesting though: Dining room/kitchen: brick red Master bedroom: Deep eggplant Master bath: Taupe Foyer: Chinese blue, then lightened to a light gray-blue Family room: Medium Gray-blue 2nd bath: Creamy yellow Living room/hall: Creamy yellow Powder/laundry room: Warm off white with black trim Office: Pale blue Guest room: Off white with hint of pink Sense a trend here? The colours are getting lighter and lighter! My favourite rooms in the house: the black and white laundry room and the almost-pink guest room :). The gray-blues are my next favourites. DH and I both grew up in homes where colour beyond beige was not really used on the walls, and then lived in some all-white apartments, so we thought we were really craving deep, confident colour on our walls. Now I'm not so sure... DH loves it, people who visit the house love it, but most of the inspiration pictures that I pull these days are of white or very light rooms. I'm not afraid of colour, but I'm developing more of a desire for the shades used in the house to be more similar to one another (they all coordinate right now, but the difference between yellow and red is not exactly subtle!) and for different spaces to be lighter or darker. We also have a lot of really interesting art and objects and we like colour and interesting textures in "stuff" (furniture, etc.), so it becomes a lot of different things vying for your attention. I don't regret painting different colours everywhere, I don't think I could have come to this realization without having done that, but now I'm debating repainting a lot of it paler, more subtle shades. More "ambiance", less "pop" and a quieter, more nature-inspired, almost Shaker-ish or Ralph-Lauren-goes-to-Nantucket style. Oh, and for the record, my house is not large - 1800 square feet or so.

I have 2 different woods and it looks fine, but I can see any of the upstairs from my downstairs. I actually have wood look tile on my first floor (I’m in Florida) and engineered hardwood on the second floor. It works.

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.

Have you looked at on line family rooms for inspiration, regarding color combinations, styles, seating options, meeting your needs and the best flow. It will give you somewhat of a jumping off point and also help with accessorizing (adding to what you have or starting fresh). Suggest doing an on line room planner with the dimensions/structural components and test different seating plans.
