Chromatic circle

The chromatic circle, created by Isaac Newton, represents the spectrum visible to the human eye and the principle of combination of colors, its contrasts and harmonies.
Primary Colors: Are pure and independent colors which cannot be decomposed, not derived from a mixture of other colors – Primary yellow, Cyan and Magenta Red.
Secondary Colors: Colors obtained from the mixture of the 3 primary colors (Ex: primary Yellow + Cyan = Green).
Tertiary Colors: Colors obtained from the secondary colors.
Cool Colors: Are associated with feeling cold and derive essentially from violet, blue and green. Are considered soothing colors.
Warm Colours: Are associated with the feeling of warmth, Sun, fire and adrenaline and derive from the yellow, Orange and red.
Neutral Colors: Among the neutral colors are white, black and shades of gray.

Color theory

The earliest theory about the colors is from the Greek philosopher Aristotle, who concluded that the colors were property of the objects. As well as weight, material and texture, they had colors. In the middle ages, the study of colors was always influenced by psychological and cultural aspects. In the Renaissance era, the nature of the colors was studied by the artists. Leonardo Da Vinci is opposed to Aristotle in saying that the color was not a property of objects, but of light.

The English physicist Isaac Newton, studied the influence of sunshine in the formation of the colors. Newton studied the phenomenon of diffraction, which consisted in the decomposition of sunlight in various colors when crossing a Prism, styling the color set as spectrum. This is formed by the union of Red, Orange, Yellow, Green, Blue, Indigo and Violet, the seven colors that make up the sunlight and that form the Rainbow.

The German writer Goethe studies influenced the subjective realisation of colours and the relationship between the colors and the psychology and physiology. The main objection of Goethe to Newton was that white light could not be made up of colors, each one of them darker than white. He advocated the idea that colors are the result of the interaction of light with the "no light" or darkness.

Behind have modified the interpretation of Rainbow, reinterpreted the colors, he renames those: purple, yellow and light blue, approaching with great precision of today's inks used in industrial printing: magenta, yellow and cyan.

Currently, the study of color theory is divided into three areas with the same characteristics that Goethe had proposed to the colors: the Physic color (physical optic), the Physiological color (physiologic optic) and Chemical color (physical-chemical optic).
