A new "Color Theory"
No doubt the Ing. Tess. Romano Dubbini (which in 1972 is in Albano S. Alessandro, F.T.R. S.p.A company for manufacture and sale of chemical products for the textile industry): the theory of colour of Harald Kueppers is truly revolutionary, unfortunate that in textbooks there is still on track.
The Ing. Dubbini explains that, unfortunately, in Italian school are taught even today the source and build the colors according to the principles of color theory of Johannes Itten, spreading this incorrect knowledge.
The painter Johannes Itten, born in Switzerland, he taught at the Bauhaus school (School of architecture and applied arts founded in Weimar in 1919). In 1961 he published a book entitled "Kunst der Farbe" (art). This work contains a selection of opinions then current on the theory of colors focused primarily on the writings of Newton, Goethe, Runge and Hoelzel. Unfortunately, while starting from a principle universally recognized based on the assumption that all physical colors of the universe (colouring) you create through the blending of three basic colors called "fundamental", Itten, in his theory, argues that the three fundamental colours, blending form all other colors are: yellow, blue and red. With the choice of this triad, exclusively subjective, that is not supported by scientific evidence, Itten elaborates his theory of colours. The three fundamental colours indicated by Itten: the yellow, blue and Red are not "primary" colours but the triad is formed by a secondary color (yellow) and two primary colors (blue and red).
To continue, Itten realizes his "chromatic circle", starting from the mixture of three colors yellow-blue-red, i.e. starting from a completely subjective assumption and wrong. In fact, if you look at a normal inkjet printer in color, ink cartridges used to make all the nuances are yellow, magenta, cyan; in addition the black; While white is the blank sheet of paper on which you print.
Thus colour admixtures Itten proposed to achieve the "chromatic circle" do not meet the expectations foreseen by the author but forcing students to adopt a color kit already formed from triad yellow – blue – red but yellow backhoe-cyan-magenta. This happens in all Italian schools where, even today, is taught the theory of Johannes Itten's Color.
At this point the Ing. Dubbini proposes simply to update textbooks replacing the color theory of Johannes Itten with the color theory of Harald Kueppers. The need for this update is due and is necessary to prevent them from continuing to inculcate in our students ' heads wrong notions that you can hardly remove or correct in their lifetime. Today the teaching of theory of colour is left to the free will of the teacher.
Already in kindergartens should explain and demonstrate the kids the difference between opaque and transparent colours; You should tell the existence of eight basic colors, i.e. two achromatic (black and white) and six chromatic colors (red – blue – green – yellow – cyan, magenta). Elementary schools all children should have a color compass, along with the usual kit of colored pencils reproducing the eight basic colors.
But then on what basis is the theory of Kueppers color? Simply on mixing three secondary colors (cyan, magenta, and yellow CMY) to create all the nuances that are used as colorants in the various activities (painting, dyeing, printing, painting, etc. etc.). Finally on the mixture of the three basic primary colors light (red-green-blue RGB) for the realization of light rays (TV-computer-neon signs etc. etc.).
The theory of Harald Kueppers color has to be updated in the sense that all lists of type RAL or Pantone colors, nowadays, indicate for each nuances, as well as the trade name of nuance and the conventional number, numeric code delivered via the RGB or CMYK values where K denotes the presence of black colour. From this important consideration, we start to apply industrially, the theory of Harald Kueppers color in the sense of being able to ricettare each shades with the mixture of only four colors formed by two secondary colors plus black and white, according to the law which regulates the mixture known as achromatic subtractive ".
The real discovery of Harald Kueppers, however, consists in having sensed the possibility of mixing a primary color with a secondary color plus black and white, according to a law that regulates the so-called "integrated mixing". This allows a reduction in costs and purest nuances and less polluting.
With such "preconditions" and with these "goals" you should update the textbooks designed for the teaching of "color Frame" in Italian primary and secondary schools.
