METHOD FOR ELECTRONIC COLOR MATCHING
First Claim
1. A method to define automatically, in a pre-selected color space, at least one user-provided sample color, the method comprising:
- (a) defining mathematically within a programmable computer at least one target color within the color space to yield a standard color data set;
(b) providing a physical color swatch corresponding to the at least one target color defined in step (a); and
(c) providing a digitized image comprising the at least one user-provided sample color juxtaposed with the physical color swatch, to yield a sample color data set; and
then (d) comparing the sample color data set of step (c) to the standard color data set of step (a) by means of a program stored on the programmable computer to thereby determine a set of coordinates within the color space that defines the user-provided sample color.

Abstract
Disclosed is a method to define automatically, in a pre-selected color space, at least one user-provided sample color. The method includes defining at least one target color within the color space to yield a standard color data set and providing a physical color swatch corresponding to the defined target color. The user then provides a digitized image comprising the user-provided sample color juxtaposed with the physical color swatch, to yield a sample color data set. The sample color data set is then compared to the standard color data set by means of a program stored on a programmable computer to determine a set of coordinates within the color space that defines the user-provided sample color.

12. A method to define automatically, in a pre-selected color space, at least one user-provided sample color, the method comprising:
-
(a) defining mathematically within a programmable computer at least one target color within the color space to yield a standard color data set;
(b) providing a physical color swatch corresponding to the at least one target color defined in step (a); and
(c) providing a digitized image comprising the at least one user-provided sample color juxtaposed with the physical color swatch, to yield a sample color data set; and
then(d) comparing the sample color data set of step (c) to the standard color data set of step (a) by determining a minimum mathematical distance between the standard color set and the sample color data set, and wherein the standard color data set having the minimum mathematical distance from the sample color data set is deemed to be the set of coordinates within the color space that defines the user-provided sample color. - View Dependent Claims (13, 14, 15, 16)

17. A method to define automatically, in a pre-selected color space, at least one user-provided sample color, the method comprising:
-
(a) defining mathematically within a programmable computer a plurality of distinct target colors within the color space, wherein each distinct target color occupies a unique location in an virtual array, to yield a standard color data set;
(b) providing a physical color swatch comprising a physical array corresponding to the virtual array of step (a), and further wherein the physical array includes a unique void array location; and
(c) providing a digitized image of the user-provided sample color inserted into the physical array of step (b), wherein the user-provided sample color occupies the void array location within the physical array of step (b) to yield a sample color data set; and
then(d) comparing the sample color data set of step (c) to the standard color data set of step (a) by determining a minimum mathematical distance between the standard color set and the sample color data set, and wherein the standard color data set having the minimum mathematical distance from the sample color data set is deemed to be the set of coordinates within the color space that defines the user-provided sample color. - View Dependent Claims (18, 19, 20, 21)
