Why they are like this?

In Hindu mythology and art, many gods, such as Krishna, Vishnu, and Rama, are often depicted with blue or bluish skin. This artistic and symbolic choice carries deep cultural, spiritual, and metaphorical meanings rather than a literal interpretation. Here are some of the key reasons:

1. Symbolism of Infinity and Cosmic Nature
Blue represents the infinite expanse of the sky and the ocean, symbolizing the infinite and eternal nature of the divine. Hindu gods like Vishnu, who is the preserver of the universe, are depicted in blue to signify their all-encompassing, cosmic nature.
2. Association with Divinity and Power
The color blue is often associated with divine qualities, such as strength, serenity, and calmness. This symbolizes that these gods possess immense power but are also calm and composed in their demeanor.
3. Spiritual Allegory
The bluish hue of the gods’ skin represents their transcendence and detachment from the physical and material world. They are not bound by earthly limitations, and their blue skin emphasizes their spiritual and otherworldly essence.
4. Cultural and Historical Representation
Early Hindu texts, like the Puranas, describe gods as having a complexion "as dark as rain clouds." Artists and storytellers began depicting this as a radiant blue to make the gods visually distinct and to convey their divine radiance.
5. Mythological Context
Some myths provide specific reasons for certain gods’ blue skin:
Krishna: His blue skin is often attributed to his divine origin and his ability to drink the poison of the material world while remaining unaffected
