1. A method, comprising:
determining a baseline optical characteristics spectrum for a stack of thin film material layers deposited on a substrate;
determining an optical characteristics spectrum for thin film material remaining in a scribe opened in the stack of thin film material layers;
determining a difference between the baseline optical characteristics spectrum and the optical characteristics spectrum for the thin film material remaining in the scribe;
selecting one or more coloring elements as a function of the difference;
adding the one or more coloring elements to a scribe fill material; and
depositing the scribe fill material into a gap opened by the scribe such that the optical characteristics spectrum obtains a minimum perceptible difference for an industry defined standard observer of the baseline optical characteristics spectrum.
