Figure 3. — Summary of the correlation of the median chromatic (chr., Col.CoV) and achromatic (achr., Lum.CoV) boldness (boldn.) and detectability (detect.) of each species with the normalized strength of chemical defences (1 – ED₅₀) across different viewing distances. (a) Individual Pearson product–moment correlations (R) for each viewing distance and colour pattern statistic. Grey shading shows 95% confidence intervals; (b) Linear regressions fitted to the Pearson product–moment correlations (R) show variable distance-dependent decreases in the correlation between colour pattern statistics.
