Figure C1 — Thresholds calculated using the image mean lookup tables. (A) Thresholds calculated using the fixed white point lookup tables (LUTs) plotted in a compact format for comparison. (B) Thresholds across the different directions of change for the five reference illumination conditions. Transparent bars represent the main effect of chromatic direction of change. They are the thresholds for each chromatic direction averaged over reference illuminations. (C) Scatter plot of the threshold data calculated using the image mean LUTs plotted against threshold data calculated using the fixed white point LUT described in the main text. All thresholds are plotted for each participant, with 20 thresholds per participant and 180 points in total.
