  1. Mean values and (Standard deviations) of ΔL, Δa, Δb of all treatment groups (T0, 1 and T1, 2)
  2. Different superscript letters indicate a significant difference between the groups within one row (p < 0.05)
  3. ΔL: difference in color shift of the white/black scale between two different time points
  4. Δa: difference in color shift of the red/green scale between two different time points
  5. Δb: difference in color shift of the yellow/blue scale between two different time points
  6. (T0, 1): difference between baseline, and directly after application of tested materials
  7. (T1, 2): difference in reading between directly after application of tested materials and after aging
