decorate my apartment

I have completely done the living room….painted a taupe color on 1 wall, bought a carpet, plants, frames, decorative objects, cushions…
Almost done the dining room, changed the placing of furnitures, bought a lamp, cabinet, got rid of crap.
In progress with bedroom, put new blinds, bedside table, have to do the bed sky.

I made a style notebook, where I cut and paste my favorite stuff, like a moodboard.
And I have mentally visualized what I would like each room to look like, depending on my needs and the room´s function.
Next….repaint my living room wall -> need to make color samples.
I´d like a blue-green with gray undertones, but it looks cold !
