One color separation.

Color Accuracy Ntest Separation
u − J 0.96 ± 0.01 518 4.1 ± 0.2
u − i 0.96 ± 0.01 536 2.8 ± 0.3
u − r 0.96 ± 0.02 536 2.0 ± 0.2
u − H 0.95 ± 0.01 510 Baseline
g − J 0.94 ± 0.02 527 Baseline
g − i 0.94 ± 0.01 548 Baseline

Notes. Column 1: tested color. Column 2: mean accuracy (proportion of galaxies correctly classified) on 100 random test sets; we notethat the colors are sorted from the highest to the lowest accuracyscore. Column 3: sample size included in each test set; differences in the sample size between different colors are due to missing data. Column 4: color discriminant value or Baseline if the accuracy score is not statistically different from the baseline classification.
