DE102006061286A1 - Color selection assembly employs a sequence of two-dimensional double-cone color cards - Google Patents

Abstract

A color selection assembly consists of a sequence of two-dimensional double-cone color cards in which the apexes are represented respectively by black and white. The colors on each card are those colors that run out in a graded sequence to white, and at the same angle from a further point to black, to an end-point. The run-out along the cone mantle follows a three-dimensional equidistant color system of brightness, saturation and color tone. The double cone mantle has a system of three coordinates, in which the Y axis shifts between white = 0 and black = 10 brightness L (luminance), the X-axis shifts between 0 and a maximum value saturation C (chroma), and a radius gains in H (Hue) about the Y axis color circle.

Description

The The invention relates to an arrangement and apparatus for color selection, which consists of a number of two-dimensional color charts. It will Patent protection for the invention requested.

Almost all common color collections or color systems are based on an arrangement of colors that is perceived to be equally spaced. The sensory distance from color to color in the 3 directions hue saturation brightness is the same. This produces rows of equally saturated or even bright colors ( 7a ).

A Combination of equally saturated However, colors or equally bright colors is of a creative nature establish not useful, because it does not fit the viewing habits and too Color fibrillates of the same color at the edges leads.

It Therefore, in each case their own color systems of the paint industry used based on a color gradation in white or black. Currently based Color combination on little comprehensible coincidences and experiences the respective designer. They are bound to the design object.

The System created here for systematic color matching for harmonic and aesthetic Aspects does not exist yet and opens up the possibility similar to the music with colors comprehensible to compose.

was in the past dealing with paints the painters, graphic designers, artists and designers reserved, so is today and in the future With the spread of the computer a diverse access to colors emerged. This is due to the increasing demand for color selection tools, as well as the constantly growing demand for aesthetic solutions, the existence of an easy to handle color selection system makes sense.

description the arrangement and apparatus for color selection

Arrangement and device for color selection consists of an interface with the associated software on a computer monitor ( 11a c).

An input device ( 11c ). An archive on a disk ( 11b ) with color-matched areas (color tone) stored as data. A hue has approximately the shape of a triangle ( 7b ). In this triangle, colors (valence) of a hue are shown in the form of color gradients, arranged according to brightness and saturation. ( 7c ) represents 2 more shades. Different brightness and different maximum saturation are shown here. A larger number of shades results in a color space in the form of a non-uniform double cone of 0-360 °. Using the input field Hue ( 11a ), the user selects a hue, which is displayed as shown. To combine several shades, the user makes input combinations ( 11a ) further shades, which are proposed according to existing laws of color theory (complementary shades offset by 180 ° opposite or adjacent, for example, offset by 30 ° shades, or all shades for a full range).

All colors used are provided by the software from the stored archive and are linked together by a coordinate system ( 8a , b).

The user searches for a color with the input tool ( 11a ). This selection point is indicated by the mouse pointer ( 11a ). By means of the X, Y values of the selection point, selection points are also recorded by the software in parallel on all loaded color tones ( 8a ).

Another selection point is mirrored on the Y axis with Y _P2 = 10 - Y _P1 again in all hues ( 8b ).

Between selection point (X _P1 , Y _P1 ) and black (Y = 0, X = 0) as well as (X _P2 , Y _P2 ) and white (Y = 10, X = 0), (X _P2 , Y _P2 ) and black ( Y = 0, X = 0) so such as (X _P2 , Y _P2 ) and white (Y = 10, X = 0) are read by the software at several points colors. Similar to a rubber band with markings which is stretched between the mentioned coordinates. This reading of colors is repeated on all active shades. If only the colors of the color space lying on the "rubber band" at the same angle to the Y axis were visible, symmetrical double-cone coats (Fig. 8c ). The colors (valence) lying on a double-cone mantle have the same brightness and saturation characteristics with each cut on the Y axis. There are 2 completely homogeneous pallets of colors created ( 11d , d2). It is understandable that these colors can be combined under aesthetic and harmonious aspects, since they contain light, dark, less saturated and more saturated colors, as the theory of colors teaches. By altering the "rubber band" further variations of the pallets can be created ( 10a , b, c). The pallets changing during the selection 11a (Display color palette) are fixed by pressing the input device.

The produced pallets can now on diverse Be used way.

The Arrangement and apparatus for color selection is an invention for Generation of coordinate based homogeneous color palettes. By application of known and new color theories is the arrangement and device for color selection for the user from various areas suitable. With the color order and selection system in no time Time harmonious-aesthetic color palettes be generated.

Reached becomes a solution the problem in that the Users of the arrangement and device for color selection a color selects and by the software a number that can be varied by the user offered by combinable colors.

Out The 3 dimensional color space becomes a manageable amount of colors extracted, which are each selected from the double cone sheath. According to the theory of colors, experience has shown that it is advantageous to combine colors which have a contrast in terms of brightness (otherwise flicker at the edges) or at equally saturated Colors are missing the ranking (you can not decide).

By The homogeneous double cone creates color palettes with an offer on colors of different brightnesses and saturations. By the combination different bicone is every conceivable color combination possible. The color suggestions can stored individually or in total, or by drag drop or input RGB values are transferred to other software. To the color in reality to be able to use The optional definition of a range of coordinates has made it manageable Number of colors set by an appropriate encoding the search for a reference color in a real color sample collection allows. Also own specialized color arrangements can be created by the user and be used.

As what has been said so far is a broad field of application imaginable. From the application exclusively in the computer, it was for graphics, Video, web design, 3D applications, computer games, cartoons etc. to over an at least genausobreite application in the real world: art, Painter-varnisher crafts, architects, retail, product design, Printed matter just to name a few.

The made invention can be used in a variety of software programs as installed alternative color selection tool. This is the majority the existing computer software. It can be used as an independent application (Stand Allone) and in combination with other programs be used. It can be used in websites for demonstration of products with different color options be used or in the paint industry as a color sample collection. These are a few examples of a large number of possible options.
