Choose art with a mood.
When you choose art for a room, I would advice you to choose art with a mood that fits the room and how you would like to feel whenever you´re in that particularly room.
If you want and need to wake up to calmness and harmony, you should go for a painting that matches the colors and textures in the room. It creates a relaxing and soothing feeling.
Some of us need might need some help and extra energy to get up in the morning, -well, then you should think about having a painting that does that to you, both in color and design. Think about what kind of feeling a painting gives you, and then choose.
