This is shown by a highly significant correlation between the blue shift and the distance of the illumination colour from daylight blue, r (39) = − 0.82, p < .001.

The correlation between Brunswick Ratio and illumination discrimination thresholds was close to significance, r (10) = 0.53, p = .08, but was positive and hence contradicted the hypothesis.
