New wedding room wall color choice

Probably introduce, because the economy is not spare, I bought the second-hand housing used by others for marriage, more than 70 square, the hut on the 6th floor by the most western side. The living room is connected to the dining room and the living room is not large. Lighting and ventilation are alright. Now I am going to get married and want to make a small change.
The master bedroom and living room are ceilings. All walls and ceilings are white.
Floor: The living room and the second bedroom are paved with light yellow tiles, and the master bedroom is covered with grey and black laminate flooring. The partitions of the entrance, the skirts, the doors, and the wardrobe are slightly darker than the color of the tiles.
Because there is no money, I just want to change the color of the wall of the living room and bedroom, as well as the color of the furniture. Some new weather.
I want to use some bright colors in the living room. I feel comfortable and spacious. (I prefer the colors of the sea and the sky. I feel like I am mentally bright. I don't know whether it is suitable for me.) There is no TV wall, only a TV cabinet. Can I put a pattern on the wall or hang a picture or something?
The bedroom is good for marriage and warmth.
There is still another thing to ask for help. I haven't thought about putting a refrigerator in the living room. Help design it (the kitchen is not good to put)
I will talk about my own views for your reference:
First, by changing the color of living room and bedroom walls and the color of furniture, the requirements for newly-married houses can be achieved. This is a feasible method.
Second, the proposed living room, because there is no design of the video wall, but you can put a TV wall with your favorite sky blue, other walls, including the restaurant wall are bright yellow.
This will bring bright, clean and spacious results. Bright yellow is a kind of light and warm color, used here is not in conflict with the sky blue and there are adjustments to dilute the cool effect, because this is the marriage room! Can not be too cold.

Two smaller abstract paintings can be hung on a blue wall. The color of the painting is preferably white or pink and yellow. It is also possible to make two separate CD grids on the wall with white paint. That is, there is a visually decorative effect of jumping and it is also practical.
If possible on one wall of the restaurant, it is best to make a three-layer shelf with a large red (or orange) shelf. If you can't do it, hang it and use a reddish pattern.
3. The western wall of the master bedroom can be light pink, while other walls are light yellow or beige, which highlights the warmth and romance of the wedding room.
The wardrobe is recommended to be white, if you can mix some pink lines (or color blocks) on the lining, it will be more harmonious with the tone of the whole room.
Fourth, the refrigerator can be placed in the northeast corner of the restaurant. There are some unsightly things in other places.
Fifth, latex paint recommended Dulux super easy to wash. This is economical because five-in-one prices are more expensive.
