  1. L value is for luminescence that represents the position on the black–white axis, a value that defines the position on the red–green axis, and b value that defines the position of the yellow–blue axis (see the details in Material and Method section). The number in the table is D values calculated based on D2 value by [3]. Asterisk (**) show the statistically significant relationship (p < 0.01) determined by GLM
