Chromaticity differences were significantly higher in group 1 (brilliant blue G (BBG) under air) than ingroup 2 (conventional BBG). The ordinate displays the CIELAB score (Euclidean distance). The upper and lower margins of the boxes in this standard box-and-whisker diagram represent the 25th and the 75th percentiles, the central line inside the box, the 50th percentile (median). The whiskers mark the minimum and the maximum, with some outliers plotted as small circles.
