Abstract
This invention is directed toward a process for producing chemiluminescent light of varying coloration and to devices which utilize the process. The process incorporates multiple fluorescers, at variable concentrations, having varying degrees of stability in peroxide. At the onset of the reaction, chemiluminescent light is generated by both the peroxide stable and less stable , e.g. peroxide unstable fluorescers, resulting in a first visible color. As the peroxide attacks the unstable fluorescer, its predominant color fades, and a different color is perceived. Inclusion of this process in chemiluminescent light producing devices results in a device which changes colors during its useful life.
