Facing colour engineers and support corps normally had a single branch colour, although exceptionally each regiment of Swedish artillery had its own facing colour until 1910. The United States regular army after the American Civil War adopted a universal dark and light blue uniform under which each regiment was distinguished only by numbers and other insignia, plus branch colors. The latter were yellow for Cavalry, red for Artillery and white (later light blue) for infantry. Combinations of colors such as scarlet piped with white for Engineers, orange piped with white for the Signal Corps and black piped with scarlet for Ordnance personnel
Light and Colour (Goethe's Theory) – The Morning after the Deluge – Moses Writing the Book of Genesis depicted their relationship in a number of his paintings, including "Light and Colour (Goethe's Theory) – the Morning after the Deluge – Moses Writing the Book of Genesis". According to this theory,the creation of colour is dependent on the distribution of dark and light reflecting through a transparent object. Turner uses main concepts from Goethe’s theory, which is a rejection of Newton's Seven Color Theory, and expresses the belief that every colour was an individualised combination of light and darkness. Newton's reasoning in his theory of light and colour was, in the words of Michael Duck, too "simplistic" for Goethe.
