The processor is also configured to execute comparing the color values of pixels representing the color reference chart of the sample image to the pixel values corresponding to a plurality of entries within a plurality of color reference datasets to determine the color reference having the closest match of sample captured in the image. The reference identifier of the color that is the closest match to the sample is then output for further use.
