Most likely Viswanath is the first indian director to provide uniforms for every member of his crew while filming. While his art staff and lightmen often wore khaki shirts and briefs, he slipped into a khaki dress for his debut film. Speaking about the same, he previously stated, "Everyone on the set of the movie wants to sit in that director's chair one day. Before accepting a job offer as a director, I worked as a sound recordist. To prevent being conceited and proud now that I have the opportunity, I have hidden myself in this Khaki clothing.
K Viswanath used to make frequent jokes about his Khaki outfit, telling several journalists that he bought it as a fallback in case his first movie doesn't do well. While creating several classics throughout his career, he only ever wore a Khaki outfit. He began his career as a sound recordist before becoming Paathala Bhairavi's assistant director in 1951. In 1965, he directed his debut film, Aatma Gowravam, in which he debuted his Khaki persona.
