Generic subjective gray point. (a) Gray adjustments of color-neutral objects in Witzel et al. (2011). The y-axis
represents the relative frequency of observers and the x-axis the first principal component of the adjustments. Gray bars
show binned scores on the principal component, and the red dotted curve shows a normal distribution fitted to the data.
(b) Binned scores of the principal components for single trials of disk adjustments are shown for observers with dress
scores below (blue bars; BK = blue-black) and above (yellowish bars, WG = white-gold) zero. Gray areas show
overlapping of bars. The blue and yellowish curves depict a normal distribution fitted to the blue and yellowish bars, and
