The p-value is the result of the Wilcoxon Rank-sum test of color distribution in terms of the brightness between (1) AS and BS; (2) BL and BS. We also measure the difference in the mean of Red, Green, and Blue intensity values. We highlight the entries to reflect that BL and BS are closer to that of BS compared to AS in terms of distance in the distribution of green and blue intensity values.
| p-value | Red | Green | Blue | |
|---|---|---|---|---|
| AS vs. BS | 3 × 10−105 | 0.02 | 0.09 | 0.08 |
| BL vs. BS | 8 × 10−218 | 0.03 | 0.04 | 0.02 |
