In a design milieu where the color yellow has been noticeably omitted for well over a decade, an out of control designer with questionable credentials in color theory has introduced such a run away use of the color as to call his (or her) physical health into question.
The color, light with a wavelength of 570 to 590 nanometers, is most commonly seen in items such as ripe bananas, canaries, daffodils, lemons and corn, and is associated with duplicity, envy, jealousy, avarice and in some cultures cowardice. Yellow has strong historical and cultural associations in China, where it is the color of happiness, glory, and wisdom. In China, there are five directions of the compass; north, south, east, west, and the middle, each with a symbolic color. Yellow signifies the middle. China is called the Middle Kingdom; the palace of the Emperor was considered to be in the exact center of the world. The legendary first emperor of China was called the Yellow Emperor.

Loggerhead sea turtle hatchlings are known to have an aversion to the color yellow, a characteristic which seems to aid them in their orientation toward oceans. Studies have shown that for humans the color yellow is difficult to read and leads to visual fatigue and in extreme cases vision loss. It has also been demonstrated to create feelings of anger and frustration. (Babies have been determined to cry more in yellow rooms than in any other color.)
Behaviorists have seen yellow contribute to aggression making subjects confrontational, and in large amounts causing irritation and anger. These symptoms were led by feelings of impatience with subjects becoming argumentative. Scientists are quick to remind that the color yellow evokes many different psychological responses and these largely differ from individual to individual, but with yellow the characteristic of it being difficult to read is more universal.
