The Karma of Colour

From Shelly Wu, PhD. Psychology on the Psychology of Colour

Yellow the pure bright lemon yellow is the most eye-fatiguing color. Light is reflected by this bright color, resulting in excessive stimulation of the eyes, causing eye irritation. It also speeds metabolism. Paint a room yellow, you will make babies cry and grown-ups lose their tempers in it. Furthermore, yellow is not a good color for notepads and monitor background. Although it can alert our brain and enhance concentration, it is hurtful to our eye.
Yellow, when used in small amount, produces sensations of brightness and warmth. It represents playfulness, light, creativity, warmth and an easygoing attitude toward life. It is as inviting as a warm, sunny day. Yellow is like sunlight -- you want it to be there to feel good, but you don't want it to be "in your eye".
Yellow has many shades. Pure yellow is the most cheerful and sunny of the spectrum. A softer tint, however, will make it more pleasant to look at. Dingy yellow represents caution, decay, sickness, jealousy and duplicity. Choice of shade is important when it comes to yellow.
Yellow, the cheerful sunny yellow, is an attention getter. It is the most visible color of all the colors, it is the number one attention getter.
Yellow is a spiritual color that is a symbol of the deity in many religions.

Blue represents solitude, sadness, depression, wisdom, trust and loyalty. Wearing blue to job interviews indicates dedication and loyalty.
Blue is one of the most popular colors. To American consumers of both genders, blue is the favorite color. However, be careful when using blue in association with food - it is a natural appetite suppressant and can be repulsive in some instances.
Blue is one of the least appetizing. Blue food is rare in nature. Blue-colored food is repulsive to humans because when our ancestors searched for food, they learned to avoid toxic or spoiled objects, which were often blue, black, or purple. During experiments, when participants were served with food dyed blue, they lost appetite.
Blue relaxes our nervous system. It has a sobering effect on the mind and can cause people to be more contemplative, which is the opposite reaction as red. Peaceful, tranquil blue, which is a good color for bedrooms, causes the body to produce calming chemicals. Darker shades of blue, however, can feel cold and depressing.
Blue surroundings, if not too dark, increase productivity. Studies show that students score higher, weightlifters lift heavier weights in blue rooms. People retain more when reading information written in blue text.
