Why Krishna is painted blue and wears peacock feather??

(the following is just one of the many explanations given to Krishna's Neela-Shyaama
Colour........would request you to do some research of authentic scriptures & come oout with more .........)

The same question was asked by a renowned spiritual leader to Dr.Rajgopalachari when he was in his school days. Then Dr. Rajagopalachari replied, "Blue signifies Infinity- the infinite sky" and lord Krishna is so - Infinite. The renowned spiritual leader was none other than Swami Vivekanannda.

The peacock feather contains all the seven colours in it. The entire universe is covered by akasha(ether) which appears blue in day times and black in night. So lord Krishna is identified by both the colours 'Blue' (neela) & 'Black' (shyaama). Krishna paksha in Indian calender means the days that follow after Full-moon day till the New-moon day i.e, the darker phase of 14 days of the moon. Further, he wears the peacock feather which signifies that the entire range of colours (we mortal beings) is in him. In virtue he is colourless but in the day he appears blue, black in the night to our vision and in between make us discuss all this multi-coloured multi-perceptional views.
