The expression “brightness reversion” has often been used for darkening that occurs after various treatments that lead to brightening. We are not in favor of this terminology because, if one component is bleached during a treatment, and another component is responsible for the subsequent discoloration, the paper may not have reverted to its original color or composition of chromophoric groups. It is important for the research laboratory to begin to ask: what is responsible for the color before treatment and what is responsible for the change that occurs as the immediate result of treatment, that which arises after treatment?
