krishna..
it can a reason thAt the one who fights against evil is depicted in
blue..
actuAlly lord krshna has a dark complexion..
usualy artists who does the images of krshna doesnt use fully dark
colours like black but prefer dark blue or even blue to depicted the
dark blissful complexion..
since as seen in iskcon also,the deity of krshna is "black" itself
some prefer to depict in white also,,n but as well..
it was according to my knowledge.
my a devo of krshna as well as an artist
