Flowchart of the ImageJ using to obtain color parameter (L*, a*, and b*). Descriptive variables (L* a* and b* ) related to color were achieved with the ImageJ software. L* variant shows the degree of lightness to darkness, a* value indicates the degree of redness (+) to greenness (−), and b* value is the degree of yellowness (+) to blueness (−) [26]. The color value of L* have shown the brightness and it ranges from 0 to 100. The color coordinates a* and b* variants do not have a particular reading range. The average values of color parameters and standard errors were calculated (L*, a*, b*, C, and H) [27].
