没有人知道我们从什么时候开始使用颜色，但我们认为古代文化可能会用颜色来代表特定的事物。人们决定颜色所代表的含义——一种文化中的蓝色可能与另一种文化中的蓝色含义相反。
人们经常选择他们不熟悉的新颜色。历史研究表明，新颜色很快就流行起来了，也许是因为它们与众不同。第一批大规模生产的汽车都是黑色的。当研发出不同颜色的油漆时，人们选择那些颜色是因为它们很新颖。第一批彩色电视机的色彩并不十分逼真，但几乎每个人都更喜欢彩色电视机而不是黑白电视机。
年龄会影响我们对最喜欢的颜色的选择。孩子们喜欢黄色。老年人似乎比喜欢红色和橙色更喜欢蓝色和紫色。这种关于颜色的知识在广告和网站设计中可能很有影响力。它会对它们的读者产生影响。
科学家发现颜色会对我们产生生理影响。例如，据说红色会使我们的呼吸和心跳加快。然而，蓝色能使我们的身体释放出能让我们平静下来的化学物质。
