No founder, founding year, or establishment record for Color TV Day has been identified. The observance appears on holiday listings and in occasional company posts, and its date matches the anniversary of the CBS broadcast of 1951, though no source documents who chose it or why.
A ruling the government's own laboratory opposed
The choice was between two designs. Goldmark's spun a wheel of red, blue and green filters at the camera, with a matching wheel at the receiver, so no standard monochrome receiver could present an intelligible picture. RCA's carried color on a subcarrier that a black-and-white set could simply ignore.
In July 1950 the National Bureau of Standards rated RCA's system superior in twelve of the eighteen categories it tested. The Commission ruled for CBS anyway, judging that further delay in getting color to the public outweighed compatibility later. RCA sued, and the Supreme Court affirmed the order four weeks before the broadcast.
