Individual coloration kinetics of berries within a grapevine bunch. Centred hue (\(H\)) kinetics were automatically computed for the n = 73 berries of the demonstration dataset. A Scaled coloration kinetics (\({H}_{s}\)) of each measured berry (grey lines), computed using their initial (\({H}_{0}\)) and final (\({H}_{max}\)) centred hue. B Relation between growth resumption time t(\({V}_{s}\)=0.15) and coloration start time t(\({H}_{s}\)=0.15). The grey line is the x = y diagonal, and the blue dotted line shows the linear regression between growth resumption time and coloration start time
