In general, persons who are nervous, hyperactive, absentminded or excitable should avoid colours that are in excessive Yang: Reds, yellows, oranges or too screaming. It would be more appropiate to use neutral and soft colours that soothe and calm down. The statistics observe that the cars with more accidents are red, the connection between stress and speed is evident. If the room is occupied by a person that is shy, apathetic, sensitive to the cold or with a tendency to depression we should avoid colours in excessive Yin. Black, dark blue, dark green, or grey shades would profoundly shoot her down. The more warm colours represented in the spring like salmon, yellow, or bright colours can stimulate the movement and be appropiate.
