"CBS had filmed the pilot for The Munsters in color, but ultimately decided to air the show in black and white to save money. The color pilot episode, called My Fair Munster, never made it to air, but was played at test screenings. Some said that leaving the show in black and white helped maintain the spookier tone, but it also ended up leading to a decline in viewers. By 1966, a full-color Batman series had premiered on ABC, causing viewership on black and white series like The Munsters to dip."
