• Scoring system of PLSR was used to explore spectral drivers of photosynthetic traits. • Green and red-edge canopy spectra reflect actual photosynthetic efficiency. • Multiple green and red peaks co-vary with QY and NPQ across experiments and species. • Pigment broadening effects may underly actual photosynthetic traits. • Statistical models may help with physical interpretation of quenching behaviour.
