2nd to 4th digit ratio (2D:4D) but not salivary testosterone concentration is associated with the overall pattern of color preference in females

The analysis revealed that the preferred color was shifted to more reddish color within blue-purple spectrum in females with high (female-typical) than low (male-typical) digit ratio. There was no association between salivary testosterone concentration and color preference either in females or males. This pattern of results indicates the possibility that organizational effect of androgen influences individual differences in color preference, giving support to the contention that biological predispositions underlie aesthetic tastes.
