Systems of additive color are motivated by the [[Young–Helmholtz theory]] of [[trichromatic color vision]], which was articulated around 1850 by [[Hermann von Helmholtz]], based on earlier work by [[Thomas Young (scientist)|Thomas Young]]. For his experimental work on the subject, [[James Clerk Maxwell]] is sometimes credited as being the father of additive color.<ref>{{cite web | title = James Clerk Maxwell | url = http://www.cis.rit.edu/node/280 | work = Inventor's Hall of Fame, Rochester Institute of Technology Center for Imaging Science | url-status = live | archive-url = https://web.archive.org/web/20100918095755/http://www.cis.rit.edu/node/280 | archive-date = 2010-09-18 }}</ref> He had the photographer [[Thomas Sutton (photographer)|Thomas Sutton]] photograph a tartan ribbon on black-and-white film three times, first with a red, then green, then blue color filter over the lens. The three black-and-white images were developed and then projected onto a screen with three different projectors, each equipped with the corresponding red, green, or blue color filter used to take its image. When brought into alignment, the three images (a black-and-red image, a black-and-green image and a black-and-blue image) formed a full-color image, thus demonstrating the principles of additive color.<ref>{{cite book | title = Exploring Colour Photography: A Complete Guide | author = Robert Hirsch | publisher = Laurence King Publishing | year = 2004 | isbn = 1-85669-420-8 | url = https://books.google.com/books?id=4Gx2WItWGYoC&q=maxwell+additive+color+photograph+register&pg=PA28 | url-status = live | archive-url = https://web.archive.org/web/20170225083437/https://books.google.com/books?id=4Gx2WItWGYoC&pg=PA28&dq=maxwell+additive+color+photograph+register#PPA28,M1 | archive-date = 2017-02-25 }}</ref>
