Pick art that has blues, greens and gold, then carry those colors into the other parts of the house. When you chose your blue and beige rug, and added blue throw pillows, you did commit to blue. Your plant is lovely, and you have some vibrant colors on your table, so try to bring more of those colors into the room with art and accessories.

This canvas print has your colors plus others so you can go in any direction.

This is a great site, fun to use, fantastic art, and reasonable prices.

The shelves don't need much of anything, they are such a beautiful focal point on their own. Try a grouping of 2 or 3 items close together per shelf.

CURTAINS you NEED CURTAINS! Pick up the blues/yellow in your rug. Get some warmth and color in that room!!!

Normally, we have lots of treasures in our homes and lots of clutter, but you lost all yours. I'm so sorry. I think you are to the point where you can slow down and allow your new memories and treasures slowly build up. I wish I still had room for my kids'art now that they have kids too. I think I remember you have kids, right? Maybe put them to work. Find a good frame shop. Bring home a few treasures from your travels. If you rush this, I'm afraid there won't be any personality. 

However, if you love that blue painting, go for it!

I don't see many ways to introduce more color without altering what you've been going for thus far... Still, I think you should break up the blue/white tendency at least with the décor around the TV - use artefacts with warmer tones. Also, you need a small table in front the couch, one where you can place a red candle on to easily change the atmosphere after turning off the lights...

Your setup looks modern and is tasteful, but perhaps also a bit too "clean" and not as "homely" as I would like... Alas, it's nothing you can't easily fix!

If you don’t want too much blue in the room, I think I would go with a wall art with green as the main color with tiny bits of shades of blue in it. Since you have the green plants.

Thank you everyone for so many good suggestions i am so surprised i didnt expect a lot of responses.

@celery that is amazing what you have done and I absolutely loved what you shared here specially orange and yellow is my fav
I cant believe only few things will warm up the place 😊

Now i have a good start i need curtains, beautiful wall art to start with. I will definitely share my progress with you all :)

Re the TV wall i am still not sure what type of pieces to put on the empty shelves and do i have a wall decor on the right side of the Tv 🤔 because i tried with plant and it didnt look good

Tee and celery, do you think it would be a good idea to repeat the wood in the TV wall in two other places? Something in wicker perhaps? Or a lighter-colored wood frame on the art behind the sectional? I have some paintings by a Hawaiian artist that are framed in a light wood. Tee, I remember you said you liked the "organic glam" look. You've got the glam part. Adding a few natural materials would help soften and cozy the overall feel. Maybe instead of the tablecloth, some woven grass placemats? Yellows, oranges, and reds are your warm colors. Orange and blue create a complementary color scheme, but any or all three of those warm colors would work extremely well with your blue, as celery showed you. You also can warm with soft textures. Think of where you might add a touch of velvet, draperies perhaps? What do you think, celery?

Before you fill up the shelves, try putting pieces in positions other than the ends of the shelves. They will look more full until you find what you want.

Tee, can you show us what you decided on? It would help us as you ask for help in other spaces.
