Table 1 Color coordinates L*, a*, and b* measured before (t0) and after the application of the treatment (t1), LCCs are calculated and displayed. Each L* a* and b* value is accompanied by its standard deviation of the mean value (SDOM). The error is calculated and reported also for the total color variation (δE*) and the L* variation (δL*) respectively
