My eight-year-old daughter is quiet and timid. What should be the main color of her room?

I think this question is mainly about how you want to raise your daughter. In fact, the influence of color on people lies in the influence of emotions. I'm not sure about this, but if you want your daughter to be safe, the main color should make her feel comfortable, and the auxiliary color can be the opposite of her personality, but it should be noted that this auxiliary color must complement her personality. This is just my personal opinion. Maybe some experts will give you advice.
