From: Discoloration of liquid foundation across the shade color diversity

\(\Delta E^*\) of foundations calculated and plotted at 0, 2, 4, 6, and 8 h-time points. \(\Delta E^*\) is most severe in brand B, followed by brand C, D, and A. \(\Delta E^*\) is largest in the intermediate shades 5 and 6 of each brand. (A) Brand A. All products only experienced minimal \(\Delta E^*\) compared with other brands. (B) Brand B. B-5 and B-6 show the greatest \(\Delta E^*\). (C) Brand C. C-5 and C-6 show the greatest \(\Delta E^*\). (D) Brand D. D-5 and D-6 show the greatest \(\Delta E^*\).
