Hi yoursra dodo, a lot of children love yellow. Yellow with a red pigment makes a room friendly and cosy. And when it is dark, rainy and grey outside, yellow cheers you up. if you select the colour, hold the sample next to the door, the floor and the blue "sky" above the bed. Look at it in dayligth (sunny and cloudy) and in the night with electric lighting.

Hi Ella, first of all, let me say that you have some really nice vintage pieces in your home! If you are planning to keep the light grey rug I would go with a darker shade of grey for the daybed and a lighter shade or a completely different color for the fabric of the sidechair (e.g. like the dark blue in your third photo) in order to create more contrast and give the room a more dynamic feel. You also mentioned a portrait to be hung above the sideboard - maybe the colors of this picture can aslo inspire the fabrics, it's always nice if the same color pops up in different details of a room. I hope this helps in your decision making process and I would love to see the results. Many greetings Anita Goda from Studio Wunderkammer

The pillowcase gives you a good impression. For me light colours do not work as good as darker ones. The petrol (right corner) would be great. But what colour does the girls love? If it is pink you go for a darker one or purple. And it is always best to test the look first. So buy just a small sample of the colour and try. If a dark colour is too dark for you, just paint one wall and the others white.

Since you are not allowed to paint the ceiling, it should be the only wooden surface in the room. The floor can be covered by either wall-to-wall carpet or a large rug, but please check if a door that opens into the room will still be operable. Multi-use and visually light furniture is important in such a tight space. I would replace the bunk bed (you're too grown-up anyway) with a nice sleeper sofa like, for instance, Flottebo. And I'd buy a comfy chair that can be used for reading and as a desk chair. It should be unobtrusive and easy to move like this feminine rattan chair. If you don't need a desk on a daily basis, I'd recommend a height-adjustable notebook table (on casters) that can double as a side table next to the sofa/ bed. Again, multi-use is the key. Once you've chosen new furniture, you can decide on curtains, rug/ carpet and other decorative elements. Wall colors are usually the last decision because you can have millions of hues individually mixed. Also consider how much natural light your room gets.
