    Abstract

    The fiber data collection in use in the Home Office Forensic Science Service uses complementary chromaticity coordinates as a method of color description. Color variation within samples is represented by an elliptical error region around the mean chromaticity point of the sample.

    For searching this collection, a method of matching single colors to the collection ellipses has been assessed. However, the necessary calculations are complex, so a number of simpler alternatives has been investigated. A simple box search has been found to be convenient, albeit with some reduction in specificity.
