Figure 3. — Results. The first row shows the choices of category prototypes (a), unique hues (b), and binary hues (c). The x-axes indicate the hue ranges and stimulus sets. The y-axis represents hue measured as the number of the Munsell chips away from the seed of the respective hue range. A unit corresponds to a Munsell hue step of 2.5. A value of zero indicates the seed of the hue range. A positive (negative) value corresponds to a clockwise (counterclockwise) hue shift away from the seed. The two bars for each hue range correspond to the first and second stimulus set. The lower row (d–f) illustrates the differences between the selection in the first and second stimulus set, that is, the differences between the corresponding two bars in the first rows. Positive differences represent shifts towards more saturated colours. Error bars indicate standard errors of mean; symbols above the bars report p values for differences from zero in paired t tests. ***<.001. **<.01. *<.05. °<.1.
