The secret of disease can be traced also by observing what a person desires in the way of food and clothing, and in what environments he prefers to be, what attitude he has towards his friends and foes, his choice of sweet and savory and his attraction to colors.

• For instance a person with a complaint that originates from melancholy will have a liking for purple;
• a person who has lost control over his passions will show an inclination towards passion, and he will generally like red;
• a person who is lifeless, who has an inclination to emptiness, will have a tendency towards white;
• a person who has gone through a sorrow and mourned over things and weakened his heart by it, will have an inclination towards black.
