Abstract

A substantially universal range of color standards over the visible spectrum is displayed for visual observation, comparison with extraneous colors and for interactive color processing in a color computer processing system. In the comprehensive set, standardized colors are defined by hue supplemented by black and white content related in a visual format. Thus, a set of discrete hue values across the visible spectrum, typically 24, is displayed in a circular array for selections of hue. Each selected hue is displayed together with a range of colors obtained by combining black and white content to produce a set of colors associated with that hue. Thus a very large number of colors may be viewed for visual effect and comparison with extraneous colors to make selections of color sets, harmonized color combinations, or the like. Any of the colors are available for interactive color processing, such as editing, graphical development or identification of colors and color relationships, either singly or in sets. Colors in objects such as paints, draperies, paintings, dresses, etc. thus could be closely identified and standardized for faithful reproduction, editing or other interactive color processing procedures such as harmonizing with related color schemes.

Claims

1. The method of displaying a set of colors for interactive viewing and processing in a color processing computer system, comprising the steps of:

organizing and displaying for selection therefrom a standardized set of more than three discrete hues distributed over a spectrum of visible hues perceivable by the normal human eye,

selecting subsets of two or more discrete hues from said standardized set,

organizing and displaying for each selected discrete hue a separate color sample set comprising for individual ones of the selected discrete hues color samples with calibrated standard amounts of both black and white content,

presenting said hues and at least one said color sample set together on a computer viewing screen for observation in a viewing mode of computer system operation to visually present color choices for selection for the respective discrete hues, and

processing said subsets of hues with associated color choices in said computer.

2. The method of claim 1 wherein the presenting step further comprises the presentation of said standardized set of discrete hues in a circular viewing wheel wherein the hues in said subsets of hues are each separated by a discrete number of steps about the wheel.

3. The method of claim 2 further comprising the presentation of the discrete hues in a set of twenty-four hues having a harmonious relationship between hues separated by 3, 4, 6, 8 and 12 steps about the circular wheel.

4. The method of claim 2 including the step of displaying the hues in said wheel in a color arrangement comprising diametrically opposed complementary hues that produce grey when mixed, the complementary hues each having a corresponding said color sample set.

5. The method of claim 1 further comprising the interactive step of selecting a color from a color image processed in the computer system for identification and comparison with the range of colors presented in said viewing mode.

6. The method of claim 5 with the further limiting step of replacing a set of colors including the selected color in the image with a set of different colors identified from the color sample sets presented in the viewing mode.

7. The method of claim 5 with the further limited steps of isolation of at least two hues from said standardized hues and corresponding color sample sets, and replacing a set of colors in said image with colors selected from said sample sets.

8. The method of claim 1 further comprising the interactive steps of identifying a set of hues from the standardized hues by visual observation, and replacing the identified set of hues with a set of hues in an image processed by said computer system.

9. The method of claim 1 further comprising the steps of editing c color presentation in said computer system by substituting a set of colors identified in the color presentation with colors chosen from said at least one color sample set.

10. The method of claim 1 further comprising the steps of:

arranging the hues in said presenting step in a circular viewing pattern on the viewing screen; and

further arranging each hue to be selectively displayed in said color sample set as a color sample, with the color samples arranged in a triangular array.

11. A computer system for processing colors in sets of discrete colors, comprising in combination, means for establishing a set of more than three discrete standard hues substantially encompassing a complete visual color spectrum in a pattern identifying therein a plurality of subsets of hues;

means for selecting processing and viewing each of the discrete hues in the set;

means for establishing and displaying for each selected discrete hue a sample set of standardized colors with a range of predetermined differing black and white components;

means for selecting a said subset of at least two desired hues incorporated in corresponding color samples from said sample sets of colors; and

means for processing color images with said subsets of desired hues in said computer system.

12. The computer system of claim 11 further comprising, color editing means responsive to replace a selected set of colors in an image processed in said computer system with a corresponding said set of alternative said standardized colors.

13. The computer system of claim 11 further comprising means for presenting said set of standard hues in a circular array having complementary hues that merge into gray diametrically opposed in a circular array and means for arranging two said sample sets of colors in triangular arrays with the complementary hues at an apex.

14. The computer system of claim 11 further comprising means for presenting said subsets of hues and said standardized colors for simultaneous visual observation, and means for selecting different discrete ones of said hues for displaying with an accompanying said sample set of colors.

15. The computer system of claim 14 further comprising means to visually array said standard hues in a circular array and said sample set of standardized colors for selected individual hues in a triangular format with a selected hue in the circular array positioned as a color at an apex and having said range of color samples in the set being arranged in said triangular format in a plurality of parallel constant white content and parallel constant black content rows incorporating a range of color samples having standardized magnitudes of constant black and constant white constituency.

16. The computer system of claim 11 further comprising interactive means for comparing colors of a color image with the standardized colors.

17. The computer system of claim 11 further comprising means for selecting said selected discrete hues from said standard set and individual color samples from corresponding sets of said standardized color samples for a color processing procedure, and means for visually identifying on said displayed colors and hues a set of activated colors and hues selected therefrom for interactive color processing.

18. The method of editing colors in a computer programmed for color editing having a color image presented thereby comprising in combination the steps of:

displaying a standardized set of more than three hues having subsets of hues arranged therein,

identifying and selecting a said subset of at least two hues from the standard set of hues for introduction into said color image, and replacing the selected hues of the subset for a different manually selected subset of hues from the color image by automated computer operation.

19. The method claim 18 further comprising the steps of:

visually displaying on a viewing screen of said computer for a selected hue a discrete set of standardized color samples, and manually selecting said modified set of hues to include one of said color samples.

20. The method of claim 19 further comprising the step of:

visually representing on said viewing screen for any one selected standardized hue a said set of color samples embodying that selected hue in a format with color samples incorporating standardized black and constant white contents.

21. The method of claim 19 further comprising the steps of:

arranging the hues and color samples together in a diamond shaped display identifying different subsets of the hue.

22. A computerized color harmonization system, comprising in combination:

a computer system for processing, viewing and editing a color image in the computer system;

means for selecting and introducing a desired hue into the computer system from a visually arranged sample set of standardized color samples comprising that selected hue having calibrated percentages of black and white content; and

means for introducing a selected standardized sample in said color image to replace a selected color in the color image.

23. The computerized color system of claim 22 further comprising:

means for presenting visually for selection of a color sample a sample set of color standards related to any chosen one said selected hue concurrently therewith, means for storing for computer processing different sets of color samples, and

means for replacing in a color image processed by said computerized system one of the color sample sets with a different corresponding set of colors in the color image.
