Take a moment and slowly start to remove colors from one of the most active and busy cities in the country. Imagine if Mumbai had its skyscrapers painted in shades of grey, the rocks at Marine Drive were jet black, cinema halls and religious halls were black n white too. Remove all colors from the city. I tried doing so, but there is no difference. The street lights sparkle the roads at night, spotlighting on different stories of the Mumbaikars, who would gather every evening for a vada pav and cutting-chai at the signal stalls.  Whatever change you bring to the city, it will just never go to sleep.
