Color difference maps of B. anthracis Ames, Y. pestis CO92, Y. pseudotuberculosis, and E. coli.
Each color represents the difference between the indicator color intensity measured before exposure and the intensity measured at the indicated detection time for each species. For visualization purposes, color difference maps are expanded from 4 to 8 bits per color (RGB range of 0–15 expanded to 0–255) [33].
