1. A color calibration system for color correction in an optical device using a database of target colors, the smart color calibration system comprising:
a physical target card;
the physical target card comprising at least three unique colored patches arranged in a predetermined pattern on the physical target card;
the physical target card further comprising identifying indicia;
the physical target card further comprising an alignment indicia; and
an executable machine readable software;
the software configured to read and assign a value to the colored patches;
the software configured to read the identifying indicia and identify the physical target card;
the software configured to read the alignment indicia for identifying individual colored patches;
wherein the software is further configured to compare color values in the optical device to known factory color values, to generate a profile assigned to the physical target card, and to convert native color space detected by the device under a specific lighting condition for use in subsequent images under the same lighting conditions.
