Some explanations of the greek word “IRIDA”:

• In Greek mythology, Irida is a secondary goddess, the daughter of Thaumas and the air nymph Electra. According to Hesiod's Theogony, Like Hermes, Iris carries a caduceus or winged staff. By command of Zeus, the king of the gods, she carries a ewer of water from the River Styx, with which she puts to sleep all who perjure themselves. Goddess of sea and sky, she is also represented as supplying the clouds with the water needed to deluge the world, consistent with her identification with the rainbow.

• That’s why, Iris, also, means in Greek, the rainbow.

• Then again, irida is a kind of flower. Iris is a genus of 260 species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, referring to the wide variety of flower colours found among the many species.

• Irida is also a part of the eye. It is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupils and thus the amount of light reaching the retina. "Eye colour" is the colour of the iris, which can be green, blue, or brown.
