Living Test Patterns: The Models Who Calibrated Color TV

In November 1953, The New York Times reported that late-night television audiences across New York had “discovered a new quiz game” on WNBT, the local NBC affiliate. It did not air on a regular basis and was not an official part of the station’s programming schedule. Nonetheless, a few nights a week, people gathered around their sets after midnight and waited for the flickering black-and-white image of a woman to appear on screen. She sat in a television studio, smiling and holding silent conversations with cameramen and engineers. The absence of a soundtrack did little to discourage viewers from staying up into the early morning, trying to figure out what she was saying, or debating the color of her hair and eyes.

It may not sound like much of a quiz, but the latter question in particular would prove remarkably significant to people at NBC during the coming months. What the public was watching, albeit in monochrome, were over-the-air tests of a color-television system being developed by the network’s parent company, RCA. Executives at NBC had hired the woman featured in these broadcasts, a red-headed model named Marie McNamara, to calibrate their cameras. “Her natural skin tones are perfect,” the producer Vance Hallack noted, “and her hair, one of the hardest colors to telecast correctly, is among the toughest tests we have.”

RCA’s public relations department soon began referring to McNamara as “Miss Color TV,” a deliberate effort to downplay the efforts of its competitor, CBS, which had used that appellation to refer to its main spokeswoman, Patty Painter. Painter and McNamara—two women sharing a common nickname—were the most prominent of the so-called “color girls,” models that different networks hired to demonstrate their new television systems. Their careers mirrored the course of one of 20th-century America’s great corporate debates, as RCA and CBS faced off to determine the technical basis for all future color broadcasts in the United States. At the same time, the selection of two white women as the literal faces of color television reflected and reinforced longstanding hierarchies of gender and race, with consequences extending well beyond the confines of 1950s America.

At its core, the dispute between CBS and RCA revolved around the best way to transmit and receive a color-television signal. After researching the question for several years, the two firms had settled upon very different answers. The CBS approach, developed by the Hungarian physicist Peter Goldmark, took an existing black-and-white television camera and mounted a rotating color filter behind the lens. The filter was divided into red, green, and blue sections, corresponding to the primary colors of light. As the disc spun, the camera captured the red, green, and blue components of an image and turned them into a television signal. A synchronized filter in the receiver ensured that a red, green, or blue filter was in place when the corresponding color information was presented on screen. Overlaying these three primary color fields on top of each other in rapid succession tricked the eye into seeing a full-color image.
