DE2723367A1 - Colour production from four primary colours - gives wide range of secondary colours by suitable combinations of red, yellow blue and violet - Google Patents

Abstract

A method of colour production departs from the traditional mixing of three primary colours, namely red, yellow and blue by adding a fourth primary colour namely violet. It is claimed that using these four primary colours corresponds morel closely to the spectrum of white light. In addition to producing orange, by combining red and yellow, andproduing green by combining yellow and blue, it is possible to produce pink by combining red and violet and turquoise by combining blue and violet. Also black is obtained from a mixture of red and blue, and white is obtained by mixing yellow and violet.

Description

Color rendering method

The invention relates to a method for reproducing nuanced color tones on coated carrier material such as films and papers, on workpiece surfaces, in textile and television technology, photography, cartography and paint and paint industry.

It assumes that the previous color rendering processes have proven to be unsatisfactory, as the reproduction often does not correspond to the original, appear alienated especially compared to the colors occurring in nature and that so far it has not been possible despite numerous attempts at mixing, a sufficient one Number of intermediate shades and thus a really true-to-life color rendering to achieve.

The reason for this situation is the fact that up to now all techniques involving color rendering on the existence of three main colors went out, although rShie helped with the prismatic decomposition of daylight of a spectral apparatus a band of colors with the colors red, orange, yellow, green, blue, violet can be perceived, the components of which make up daylight. It is common to use the colors blue, yellow and red as the main colors to designate, since they cannot be obtained by any mixtures, while green can be obtained from blue and yellow and orange from yellow and red. On the other hand, the violet hue, which was assumed to be made of blue, was ignored and red arises and consequently as a third transition color alongside green and orange is to be seen. However, this assumption turned out to be incorrect. She disagreed both of logic after the first and second transition colors are green and orange respectively can be obtained from their two neighboring spectral colors, which is not the case with violet is the case because it is on the edge of the color scale. It also has been in practice has shown that mixing red and blue by no means gives a pure purple can be. Consequently, the hue of purple has the same properties as that previously referred to as main colors and is therefore to be regarded as the fourth main color.

The invention builds on this knowledge and accordingly teaches the Reproduction of nuanced color tones through the use of four basic color components blue, yellow, red and purple and thus one that has not yet been achieved Variety of two colors that actually occur in nature, to be able to produce or reproduce.

In a further embodiment of the invention, the mixture becomes more appropriate Proportions of two basic colors, the transition colors rust, orange, green and turquoise as well as black and white achieved in or on the respective color carrier, so with the addition of six transitional colors to the four main colors, there is already one Duplication of color rendering possibilities achieved. That becomes the fact Into account that in nature not only the rainbow colors exist, but next to it also black and white, which is due to the mixture of different colors with each other involved must be observed.

The same applies to those provided in a further development of the invention Achievement of a medium gray tone by mixing equal proportions of the basic color components blue, yellow, red and purple, its inclusion in the color rendering as well contributes to an enrichment of the color variety and color naturalness.

In addition to the previously mentioned color composition options, according to the invention nor the production of a white shade by the mixture of yellow and purple as well as the creation of a black hue through the mixture of red and blue, i.e. two in each case in contrast to one another Colours be made, the production of the two colors black and white insofar is of particular importance as it is the naturalness and accuracy of the image reproduction to a large extent determined by their light and shadow effects.

The figure shows the color scheme on which the invention is based, on the basis of which further details of the invention are to be explained. In the The four main color components within the circle are red, violet and blue and yellow, while the transition colors are named outside the circle, which can be obtained by mixing adjacent colors, namely rose from red and purple, turquoise from purple and blue, green from blue and yellow and orange from yellow and red. The figure further illustrates that through Mixture of two diagonally opposite colors in a circle further transitional shades can be obtained, namely black from red and blue as well as white from yellow and purple. So we have a total of four main colors, four Intermediate colors as well as black and white, with contrasting colors facing each other, namely rosifind green, orange and turquoise, purple and yellow as well as red and blue Mit these basic main colors as well as the six that can be achieved by mixing them nuanced color rendering can be achieved with important transition tones However, it should be noted that the main colors each have a corresponding wavelength must have, so no unwanted Color change occurs.

Among the colors mentioned are two from the standpoint of their psychological Effectively referred to as warm colors, namely yellow and red, as well two cold wrinkles, namely purple and blue. The other hand are two of those colors extremely bright colors, namely yellow and purple, as well as two shadow colors, namely red and blue. When the four basic color components are on their corresponding Wavelength are set, they have an amazing light-shadow effect. So one can say yellow as the luminous color of red and violet as the luminous color of blue denote, the two luminous colors to a certain extent a positive one, the two Shadow colors, on the other hand, have a negative character. The two have Luminous colors violet and yellow have the same luminosity as well as the two shadow colors blue and red the same darkness. However, as is known, the layman succumbs Daylight is an optical illusion in that it is darker than violet; yellow feels and feels red as lighter than blue. On the other hand, the black-and-white-sensitive is subject to Photo paper does not have such an optical illusion and gives the luminosity of the different colors realistically.

Compared to the processes that used to work with three main colors the method according to the invention, which is based on four basic color components, is essential Advantages taking into account the fact that all colors are in certain relationships to each other stand: 1. a contrasting relationship (between warm light / cold light and warm shadow / cold shadow); 2. a harmonious relationship (between warm light-warm shadow and cold light-cold shadow) and 3. a dissonant relationship (between warm-light-cold-shadow and cold-light-warm shadow).

The colors, for example, are in contrast to one another yellow and purple as well as red and blue, there is a harmonious relationship between yellow and red as well as violet and blue, a dissonant relationship on the other hand between the colors yellow and blue or purple and red.

By mixing different colors in a certain ratio to each other, a multitude of color nuances can be obtained, the o a finely graded reproduction Any templates are allowed and in addition to the purely optical display option of pictures, patterns and the like on different types of color applications, specific psychological Impressions such as warmth, cold, depth of space, tension and the like can express.

For example, if you mix the four main colors blue, yellow, red and violet in equal proportion to each other, an eleventh color is obtained, which can neither be addressed as light or shadow nor as warm or cold color and represents a medium shade of gray. On the other hand, if you mix the two together harmonizing warm colors yellow and red, you get orange, which is neither one Light is still a shadow color, but simply perceived as a warm shade will. By mixing the two harmonizing cold colors, namely violet and blue, on the other hand, creates the shade that is perceived as extremely cold turquoise. The comparison of orange and turquoise consequently results in a maximum achievable color contrast.

By mixing the two dissonant colors yellow and blue a green color is obtained; from the dissonant colors violet and red, on the other hand, is a shade of pink, the juxtaposition of these two colors, green and rosé result in a pronounced contrast effect, with the help of which, for example, the Depth of space can be expressed in a picture reproduction.

Finally, if you mix the two that are in contrast to one another Yellow and violet colors result in white, but by mixing blue and red, on the other hand, it is obtained black and these two mixed colors white and black determine the light and shadow side of the picture.

By mixing any three main colors with each other, one can create a new color scale can be obtained as shown below: yellow + violet + red = dawn yellow + violet + blue I sky color red + blue + yellow o Earth color red + blue + violet = sea color.

The four mentioned colors of the secondary color scale are extraordinary important because in nature it is not the main colors that appear, but rather the color tones corresponding to the secondary color scale. By mixing the different colors this secondary color scale can again be used as above with reference to the example the four primary color components described six out of the four secondary main colors secondary transitional colors produced by mixing appropriate color components and thus the variety of reproduction and expression possibilities again expanded will. This secondary color system also contains two distinctly light colors, namely dawn and sky color and two shadow colors, namely earth color and Sea color, as well as two warm colors (morning red, earth color) and two cold colors (Sky color, sea color).

With the four basic color components and the four secondary colors as well the transition tones that can be achieved by their mixture are extraordinary rich color range to reproduce any subtleties in the color nuances and to represent the richness of colors of nature.

With the method according to the invention it is therefore possible to do the previously well-known color reproduction process to improve and really make a decisive difference perfect representation of natural originals especially in film and television possible close. In addition, with the application of the method according to the invention in other Industries, such as paint and paint technology, textile and Clothing industry, cartography, printing and here in particular the specialty of the art print, the variety of colors and possibilities of expression expanded considerably and created the basis for every color nuance occurring in nature and mood can be expressed.
