Sri Krishna is depicted having blue skin color. Why is he
not shown in normal human skin color? Hinduism is full of symbolisms and the
blue color is also a symbol.
Blue is the color of the infinite. All Hindu gods are an
attempt by the human mind to give form to the formless Brahman (The Supreme
Truth or God in Hindu Religion). The color blue symbolizes immeasurable and all
pervading reality – formless Brahman.
Swami Chinmayananda talking on the subject says that
whatever is immeasurable can appear to the mortal eye only as blue; thus the
cloudless summer sky is blue to us because the endless distance of space is
interpreted by the physical eye as blue in color.
The blue color thus teaches us that what appears as Krishna is the all pervading reality. Brahman (the
Supreme Reality) takes a particular form to satisfy the human mind.
