@ “The color yellow is a spontaneous and unstable color. It is often associated with food and is highly used in children’s products and marketing advertisements aimed at children. Perceived as a childish color by men, yellow is not a color that should be used when marketing products to prestigious or wealthy men.
If yellow is overused, it can have a disturbing effect. For example, it is a proven fact that babies cry more in rooms painted yellow. Too much yellow causes loss of focus and makes it hard to complete a task. Too much yellow also can cause people to become critical and demanding. Too little yellow causes feelings of isolation and fear, insecurity, and low self-esteem. A lack of yellow can cause one to become rigid, cunning, possessive, or defensive.
Yellow gemstones are believed to aid in clarity for decision-making, boost concentration, increase energy, and offer relief from burnout, panic, nervousness, or exhaustion.
In different cultures yellow has different meanings. In some cultures, yellow represents peace. In Egypt yellow was worn to signify the dead. In Japan, yellow stands for courage. In India, yellow is the color of the merchants.” (bournecreative.com)
