The Osirian Mysteries – These mysteries were associated with the god Osiris and the cycle of death and rebirth, reflecting deep beliefs about the soul’s journey and transformation.

For example, the triad of Osiris, Isis, and Horus was very prominent in Egyptian mythology, each member representing different aspects of life, death, and resurrection.
Egyptian Mythology: Another example from Egyptian mythology, apart from the previously mentioned Osiris, Isis, and Horus, is the trinity of Amun, Ra, and Ptah.
The Heliopolitan Triad: Centered around Osiris, Isis, and Horus, this is one of the most famous Egyptian triads and is often linked with themes of death, resurrection, and kingship.
Osiris was a god of the underworld and resurrection, Isis, his wife, a goddess of magic and motherhood, and Horus, their son, a god of the sky and kingship.
The Abydos Triad: This triad included Osiris, Isis, and their son Harpocrates (Horus the Child).

Blue was also associated with the sky, and may have represented the idea of resurrection and the afterlife, which were also central to Osiris's mythology.
It's possible that the blue skin of Osiris was meant to evoke this connection to the underworld and the afterlife.
Depictions of Osiris with blue skin are relatively rare in ancient Egyptian art, and most depictions show him with green or black skin, which was more commonly used to represent fertility, vegetation, and rebirth.
