In Hindu mythology, the color blue is often associated with the divine, and particularly with Vishnu, one of the principal deities of the religion. Vishnu’s blue skin symbolizes his vastness and infinite nature, much like the sky and the oceans, which are both blue. This color signifies not just the physical aspect but also the spiritual essence of Vishnu.
Furthermore, blue is symbolic of the qualities of calmness, tranquility, and preservation. Since Vishnu is known as the protector and preserver of the universe, his blue skin acts as a reminder of his role in maintaining balance and order in the world. The hue also serves to highlight his divine qualities, distinguishing him from mortal beings and evoking a sense of awe among his devotees.
In art and iconography, the portrayal of Vishnu with blue skin helps followers to recognize him and connect with his divine attributes. Thus, the blue color is a multi-faceted symbol, representing both Vishnu’s nature as the preserver and the eternal, boundless aspects of his divine essence.
