Values reported describe the number of patches (out of 15) without any discernable dichromatism (just-noticeable-differences < 1) under the first set of conditions (Condition 1: < 1 JND) and under the second set of conditions (Condition 2: < 1 JND), the number of patches that changed by more than 1 JND when comparing the first and second set of conditions (> 1 JND change), the maximum dichromatism value change for a single patch (Maximum change in JND) and its percentage change (Maximum change in percentage); NA values indicate that the score under one of the conditions is < 1 JNDs.
