Some topics are off-limits in art as in life, as indicated by the artist's choice to include a hidden canvas. At the same time, Wittawat himself uses various imagery to signify the sensitive and the taboo, resisting the urge to conform, or rather turning the tables on the conformists, by representing a series of colours nowadays associated with political leanings. Red, yellow, blue or green hues all have political connotations, but after the passing of King Bhumibol Adulyadej, even black -- especially black clothing -- became an unwritten but nonetheless mandatory norm. In a sometimes black-and-white manner, one set of beliefs is portrayed as a fading shadow, a static and lifeless vision belonging to the past, symbolized by smoke or a calcified rock, ready to crumble at any given moment.
