ABSTRACT:
A package for a granular material, such as a laundry detergent, is provided. The package includes a closed bottom container for storing the granular material and an opening through which the granular material can be viewed. A radiant structure, such as a paperboard liner, is disposed within at least a portion of the container. The radiant structure has a radiant structure characteristic, such as the spectrophotometric curve of the radiant structure. The radiant structure characteristic is selected to produce a predetermined shift of a radiant material characteristic of the granular material, such as a shift in the spectrophotometric curve of the granular material.
