In Greek mythology Helios, the sun god, rode across the heavens on a golden chariot pulled by four fiery horses. Our modern day associations with the color yellow, and its close cousin orange, are equally positive—if slightly less dramatic. Both make us think of bright sunshine, fresh citrus, and the abundance of fields at harvest time. But there‚Äôs a harsher side to the shades: in the animal world, yellow (often combined with black) signals the danger of an animal or insect likely to sting or bite. Yellow can also bring to mind dry deserts or withered leaves, which in turn have come to symbolize declining power. In Buddhist and Hindu teachings orange, the midpoint between yellow and red, signifies the point of balance between libido and spirit. But Christianity once took a differing view of the color, associating it with greed or gluttony.
