yellow
Yellow is sunshine. It is a warm color that, like red, has conflicting symbolism. On the one hand it denotes happiness and joy but on the other hand yellow is the color of cowardice and deceit.
For years yellow ribbons were worn as a sign of hope as women waited from their men to come marching home from war. Today, they are still used to welcome home loved ones. Its use for hazard signs creates an association between yellow and danger, although not quite as dangerous as red.
If someone is yellow it means they are a coward so yellow can have a negative meaning in some cultures.
Yellow is for mourning in Egypt (egypt = pyramid= uri?= luxor hotel?) and actors of the Middle Ages wore yellow to signify the dead. Yet yellow has also represented courage (Japan), merchants (India), and peace.
Yellow is vibrant and friendly. The color of sunshine, yellow represents happiness, joy, good humor, intellect and energy. Yellow evokes feelings of warmth and cheerfulness. However, yellow should not be overused, as vast expanses of bright yellow creates a disturbing mental effect.
Yellow attracts attention very effectively. Yellow is especially good for attracting customer attention when mixed with black. Note how toxic signs and other warning signs tend to use yellow and black. Conversely, it works poorly on white and tends to disappear into white. Yellow needs to be contrasted with a dark color.
In marketing, yellow stands for ‘low priced’; as you might have noticed, this color is used by Subway, McDonald’s, Cheerios. Yellow is usually seen as light-hearted, unstable, and a little childish. While this color works well for promoting children’s products, yellow is unsuitable for promoting high-end items targeted at the upper echelons of society. Few people will buy a yellow purse or briefcase.
