First Claim
1. A computer-implemented method, comprising:
- displaying, via one or more processors, a positional overlay framing a digital image of a siding sample to be taken with an image capture device, the positional overlay including a color card reference area and a region of interest indicating a portion of the siding sample that has a first color value,wherein the positional overlay indicates instructions for (i) a distance to be maintained from the siding sample with respect to the image capture device, (ii) an orientation of the siding sample with respect to the image capture device before the digital image is captured, and (iii) a determination of a correct physical placing of a color reference card having a reference color value on the siding sample;
capturing, via the image capture device, the digital image at the distance, orientation, and correct physical placing of the color reference card according to the instructions;
color normalizing, via one or more processors, the digital image based upon the reference color value of the color reference card positioned within the color card reference area, the color normalizing resulting in the first color value within the region of interest being adjusted to a second color value;
calculating, via one or more processors, a set of spatial distances representing a difference between (i) the second color value plotted as a calculated quantified color point within a color space, and (ii) each known quantified color point from among a set of known quantified color points within the color space, each known quantified color point being associated with a respective replacement siding product from among a plurality of replacement siding products; and
determining which of the plurality of replacement siding products has a color that is a closest match to that of the siding sample by identifying, via one or more processors, which of the plurality of replacement siding products produces the shortest spatial distance from among the set of spatial distances when compared to the calculated quantified color point.

Abstract
The method and system may be used to provide an indication of a color value for a particular siding sample and to color match a specific siding product to the color value of the siding sample. The system receives a digital image of a siding sample and a desired color value to be matched. A color query module plots this desired color value as a desired color point in a multidimensional color space together with a plurality of color reference points. Each color reference point represents the color value of an existing siding product. The system determines a “distance” between the desired color point and each plotted color reference point within the color space and identifies the siding product associated with the color reference point that is located the shortest distance to the desired color point within the color space.
