As you might already know, Greek and Roman statues were made from marble. What you might not know is that most of them were painted but with time, plaint disappeared. During the Renaissance, artists started to use marble to make white sculptures since they thought it was how they did during the antiquity era. Besides, Egyptians did like white because it was a color associated with dawn and festivities.
White is, after red and blue, the third most used color on national flags. It has different meanings too. It can represent peace, purity, religion or harmony, for example. The two white stripes added to one larger black stripe on Botswana’s flag are related to harmony between people and the zebra, their national symbol. On the Icelandic flag, white is associated with snow and winter, while on the Irish flag, it is associated with peace.
