The mean preference scores of the independent variables at different levels (blue dye colour, floral pattern size and pattern type) are presented in Table 2, and the ANOVA results are presented in Table 3. In terms of effect size, The largest partial eta square value in Table 3 is Pattern (0.08), followed by Colour, Size and Size \(\times\) Pattern (all about 0.01). Since most of the Power values in Table 3 are greater than 0.8, indicates that the sample size is adequate, and represents the probability of avoiding the Type II error. The ANOVA results indicate that the main effect of blue dye colour was significant (\(F_{6,12768}=11.73\), \(p<0.01\), \(\eta^{2}=0.01\)), and the results of [PERSON]'s post-test at \(\alpha=0.05\) show that the subjects exhibited the strongest preference for B9 (2.71) and B14 (2.70) and the weakest preference for B22 (2.48) and B18 (2.50) (see Table 4). \begin{table}

Table 3: ANOVA of blue dye colours, floral pattern sizes and pattern types. The interaction between indigo colours and pattern types was also significant (\(F_{6,12768}=2.93\), \(p<0.01\), \(\eta^{2}=0.00\)). Figure 5 shows that the subjects' preference for the 2-D pattern was always stronger than that for the 1-D pattern; however, with the darkening of the indigo colour, the difference in preference declined. The main effect of floral pattern size was significant (\(F_{3,12768}=58.91\), \(p<0.01\), \(\eta^{2}=0.01\)), and the results of [PERSON]'s post-test at \(\alpha=0.05\) demonstrated that the subjects exhibited the strongest preference for the large pattern size (L, 2.81) and the weakest preference for the extra small pattern size (XS, 2.44) (see Table 5). The interaction between floral pattern size and pattern type was also significant (\(F_{3,12768}=54.95\), \(p<0.01\), \(\eta^{2}=0.01\)), and Figure 6 shows that the subjects' preference for the 2-D pattern was maintained at a stable level (2.91-2.97). However, with decreasing floral pattern size, the preference for the 1-D pattern decreased (2.66, 2.32, 2.16, 1.92).
