Abstract
An apparatus, system, and method for producing a temperature exposure indicator is disclosed. The temperature exposure indicator includes a substrate and a mixture containing a first thermochromic material and a second thermochromic material. Each thermochromic material has an initial color state when the mixture is in a base temperature range and each thermochromic material is configured to change to an excursion color state at a certain temperature threshold. As a result, the mixture displays a low mixture excursion color state below a low temperature threshold and a high mixture excursion color state above a high temperature threshold.
