`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.`

`593, 600, 610, 628, 651, and 674 nm, i.e., the lights were in the red-`

`average of the observed values.`
