Try doing an accent wall first was the blue might be too overpowering.

Start with one or two walls and see what you think. That dark/bright of a color might make the area seem very dark.

I painted my living room, dining room, kitchen and entryway a fern green with light orange accent walls. I absolutely love it as the colors go so nicely together. I'm sure your orange dining room will be beautiful.

I'm using yellow as the accent color in my bedroom, but haven't gotten that far yet. I love how bright colors energize a room, and lift my mood. Good luck on your projects.

Please no accent walls. Make small rooms look choppy, not done. You are picking very bold colors. Which is fine, if you truly love them. Painting entry a dark or royal blue, will be too dark. For a room with more windows. Is color we see on side the color you are thinking? Hard to tell true colors on a computer. It looks blue/gray? If you like it, paint all entry same as side wall. In other rooms I would take that shade and work with it in all rooms. Just use 2 shades dn or up on color chip. A variation of same color, will give you a consistence though out. Then use your other color ideas for rugs, accessories, art. There are so many ways, to bring all rooms together. Ceilings because they are low. Should stay white as well as trim.

Because of the tile. Which makes room look cold. I would go for some bold print area rugs. 8x10 in front of sectional. Add bold pillow color from rug to sofa. Also, Under dining table. A 5x7 for entry. Place 2 feet from front door. In office a sisal rug big 8x10 push under desk. You might be able to arrange furn better. No small items in entry like you have, no small art on walls. Use big palm in nice pots to fill corners . A small table in entry with a big mirror would finish that area.

I would remove verticals shades on all windows. Go a simple panels on ends only. You could go a print, like Greek key design.

I'm not sure royal blue and your dark, warm woodwork would be a good fit. How about a warm dark gray color?

Benjamin Moore Iron Mountain is a good one.
