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.
