I always like some cool in the home so when bodies are in the room there will be balance. I think we miss the element of humans in a room as a color element.
a good video, but imho grey is a horrible colour to have as a main feature in your home. I find it depressing - like a cloudy day - every day. ok in small doses to enhance other colours, but not - as in a flat i just bought - everything all grey ☹️.
