Confidence in the future: green 26%, blue 17%, …

A semantic connection between fate and the idea of charity can be found in the mythology of the Slavs. The Vily, a Slavic mother goddess and pagan clan goddess, who always manifests herself in threefold, brings happiness and prosperity to young people. At night they enter the homes of righteous people to do housework. They take care of the single widow’s child and work in the garden to grow fruit. (Vyncke, 1969)

In China, green is also the symbol of longevity and mercy.

Everything is sprouting, all germinates, everything is turning green. Green is the colour of spring. In a transferable sense, green is the colour of flourishing. When in an old text it said: “at the time that Rome was the greenest”, it did not mean Rome in springtime but Rome in the time of its economic and cultural prosperity.

Green was the favorite colour of the prophet Muhammed. He was wearing a green cloak and a green turban. The most precious relic of Islam is the Sanschak-i-Scherif, the sacred banner. It is green with gold. It is the flag with which the prophet went to war and finally conquered Mecca. The fact that Muhammed proclaimed green to be his favorite colour was no coincidence that depended on his own taste. Muhammad (570-632) announced the revelations of the only god as they were explained in the Quran. He predicted the believers as wages for a godly life not ascetic and hypocritical hereafter, but a paradise full of sensual pleasures (Jannah). A life full of delight in enchanting landscapes, on flowering meadows, in shady forests and eternal oases. Green would be the dominant colour in paradise. This was and is a representation that raptures desert people. In the middle of the desert, green nature is overwhelming. It means the same as material and spiritual prosperity.
