Title: Colors B Matrix
Source: Ekman (1963)
Description: Preliminary (non-symmetrized) B matrix based on Colors
data set. Six monochromatic lights of equal brightness served as
stimuli. Their wavelengths were 593, 600, 610, 628, 651, and 674 nm,
i.e., the lights were in the red-yellow range. All possible pairs of
lights were projected onto a screen, and ten subjects were asked for
"contained-in" judgments on each pair.

Title: Colors H(2) Matrix
Source: Ekman (1963)
Description: H(2) Matrix based on Colors data set. Six monochromatic
lights of equal brightness served as stimuli. Their wavelengths were
593, 600, 610, 628, 651, and 674 nm, i.e., the lights were in the red-
yellow range. All possible pairs of lights were projected onto a
screen, and ten subjects were asked for "contained-in" judgments on
each pair. The table contains the values v_ij/v_ji, where v_ij is the
average of the observed values.
