Fig. 4: Segmentation of CIELAB grid (n = 5693) of 4-unit bins at 8 lightness levels into 7 Himba colour terms: serandu (red) 34.5%, grine (green) 23.2%, burou (blue) 22.9%, zoozu (black) 8.1%, dumbu (yellow) 7.7%, vapa (white) 3.5% and vinde (brown) 0.2%.

The position of the newly identified term vinde is shown on two lightness levels. Disc size corresponds to the confidence of classification by the RST algorithm for the new data. The colour of each disc corresponds to the centroid of each identified colour term.
