Figure 3

Relationship between carotenoid-based colouration (chroma) and detectability (visual contrast) against all backgrounds. Detectability was computed against average brown (above) and green (below) backgrounds computed for each plant species separately using parameters for V-type eyes (results for U-type eyes are very similar) pooling all three species and both green and yellow plumage patches. Depicted are LOWESS regression lines (see [92] for a detailed explanation) for each plant type. Figures depicting this relationship for each background type separately are found in Additional File 4.
