Light spectrum, from Theory of Colours – Goethe observed that colour arises at the edges, and the spectrum occurs where these coloured edges overlap.. Theory of Colours (German: Zur Farbenlehre) is a book by Johann Wolfgang von Goethe about the poet's views on the nature of colours and how they are perceived by humans.
A color wheel or color circle [1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms color wheel and color circle interchangeably; [ 2 ] [ 3 ] however, one term or the other may be more prevalent in ...
According to this theory, the creation of colour is dependent on the distribution of dark and light reflecting through a transparent object. [5] Turner uses concepts from Goethe's theory, which is a rejection of Newton's Seven Colour Theory , and expresses the belief that every colour is an individualised combination of light and darkness.
Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.

Schopenhauer's theory, however, claims that yellow is ¾ as bright as white. Orange is 2/3, red is ½, green is ½, blue is 1/3, and violet is ¼ as bright as white. The external cause of color is a diminished light that imparts just as much light to the color as it imparts darkness to the color's complement.
The right column undergoes a dramatic change in perceived color. Lightness is a visual perception of the luminance of an object. It is often judged relative to a similarly lit object. In colorimetry and color appearance models, lightness is a prediction of how an illuminated color will appear to a standard observer. While luminance is a linear ...
