Black is back as Thais mourn revered king

On his birthday Thais wore yellow, when he got sick they put on pink, and now that King Bhumibol Adulyadej has passed away Bangkok's streets have turned monochrome in an extraordinary display of collective grief.

The venerated monarch died at the age of 88 on Thursday, plunging the nation into mourning and leaving a politically divided people bereft of a rare unifying figure.

Thailand is a country that leans heavily on symbols and people have long expressed devotion to the king through clothing, with many in Bangkok sporting yellow every Monday, the day he was born.
