Two-way ANOVA ( Table 2 ) indicated that white-light pretreatment duration had highly significant effects on L*, a*, and b* ( p < 0.01), whereas blue-light irradiation duration significantly affected L* and b* but not a*.

Although the interaction between pretreatment duration and blue-light regime did not reach statistical significance ( Table 3 ; F = 1.76, p = 0.195), these contrasting patterns suggest that the optimal blue-light strategy depends on whether white-light pretreatment is applied.
