Primary Colors part 1
Correction: An earlier version of this episode incorrectly stated the Jacob Christopher Le Blon was the first to identify cyan, magenta, and yellow as the three subtractive primary colors in 1723-26. Le Blon invented three and four color printing, but used red, yellow, and blue as his primaries. It wasn't until 1905 when Thomas A. Lenci of the Eagle Printing Ink Company, in New York City, used cyan, magenta, and yellow as his primaries and the CMYK method was invented. Send us Fan MailSupport the show
