Orange (colour) Orange (colour) Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In painting and traditional colour theory, it is a secondary colour of pigments, created by mixing yellow and red. It is named after the fruit of the same name. The orange colour of carrots, pumpkins, sweet potatoes, oranges, and many other fruits and vegetables comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical
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.
