पीली पीली सरसों फूल  (Yellow are the mustard flowers)
पीली उड़े पतंग (The flying kite is yellow)
ओ पीली पीली उड़ी चुनरिया (The chunariya that flies is yellow)
ओ पीली पगड़ी के संग  (along with the yellow turban)

Vasant Panchami or the beginning of the spring season is on the 5th day of the waxing moon of Magh i.e. 12 February 2016 and is celebrated in the Northern part of India.

The colour yellow is associated with the day, be it clothes or rice coloured with saffron.

Also the day for worshipping Saraswati in some parts of the country e.g. Bengal. And in days past the day for a festival in honour of Kamadeva aka the God of Love, though the celebration shifted with time from April to the beginning of spring and is no longer celebrated.
