The Significance of Rug Colors

Green, being a holy colour, was forbidden for use in ground colours (unless Prayer Rugs), until the 1930s, when commer­cial weaving under foreign pressure for export, demanded its introduction.

Each colour has its own meaning:
Black—Revolt, destruction.
Brown—Good harvest, fertility.
White—Purity and peace and colour of mourning.
Red—Happiness and joy.
Green—Spring and re-birth.
Sky-blue—National colour of Persia, and colour of mourning.
Indigo—Solitude.
Purple or violet—The king's colours.
Gold—Wealth and power.
It is not difficult to see how each colour derived its meaning, for example:
Green—spring, re-birth and paradise, spring is easy to under­stand—and re-birth as well, as the flowers are re-born amidst the greenery, paradise must certainly be green.
Brown—earth must mean fertility.

And so on, each having its own simple meaning, simple and primitive maybe, but are not we all in many ways.
