Data are presented as mean ± standard deviation (n = 12). Different letters represent significant difference between means within each column (p < 0.05; ANOVA test, Tukey-HSD post hoc test). L*: lightness from black (0) to white (100); a*: red–green colour (a* > 0 indicates redness, a* < 0 indicates greenness); b*: yellow–blue colour (b* > 0 indicates yellowness, b* < 0 indicates blueness).
