I'm getting my room renovated, I'd like some advice on the painting colours please?

Okay, so here’s the thing. We’re getting part of my house renovated and I’m getting a whole room for myself (yay to that). And since the room is mine, I can choose what colours I’d like it to be. But I’d like some advice on that. First, here are some pictures of the room.

This is what the renovated part of the room will look like. It’s basically the balcony which is being converted into a room (as you can see, lots and lots of windows for lots and lots of light).

The floor is going to be like this (ignore the blue carpet, it’s what the workers have laid on the floor). As shown in the picture, the floor is parquet. We’re gonna keep it like that and extend the same flooring to the new part of the room.

And in the room, we’re gonna keep some cabinets and drawers which look like this. As you can see, they’re blue in colour. And the plastic-covered section has been done like that to protect the encyclopedias and stuff inside that cavity.

And if you guys are still confused, I took the time to draw up a somewhat accurate floorplan of the room here. As the floorplan shows, one of the reasons why I claimed this room is the fact that it has a toilet attached to it (so I don’t need to disturb others late at night when I need to use it).

Now, I’ve always wanted a room to be nice and bright, so I actually always pictured it with a nice yellow wall (although I wouldn’t mind a nice serene green too). A few online tests I took for ‘paint personality’ gave me similar results. Like this and this. However, I’m just wondering how in the world I can get the walls and ceilings to match with the brown parquet floor and the stupid blue cabinet (which my parents say we won’t remove).

I’m throwing this question open because I feel that I’m in a bit of a fix here. So if you’ve read up till here already, could you please spare some kind thought for this guy here and give some advice? It’s fine if you give me other colours than yellow or green, just tell me what you think is best for this room of mine.

Much much much appreciated…
