  text: Mica-titania pearlescent pigments (MTs) were previously coated with organic
    molecules to obtain combination pigments (CPs) for achieving certain improvements
    or functionalities. Anthocyanins (ACNs) are molecules that can be extracted from
    natural resources and exhibit color changes via pH modifications of the enclosing
    medium. The purpose of the study was to produce a new series of CPs by depositing
    ACNs on MTs at different pH values, to observe the changes in color, and to associate
    these changes to thermogravimetrically determined deposition efficiencies in light
    of spectral differences. The extraction and deposition methods were based on aqueous
    chemistry and were straightforward. The ACN deposition generally increased with
    increasing pH and correlated with the consistency between the charges of the MT
    surfaces and the dominant ACN species at a specific pH value. The fluorescence
    of the CPs was inversely correlated with the deposition quantities invoking the
    possibility of a quenching effect.
