but only in-vitro (solvent) - in vivo it's actually not that pronounced.
this is one of the greatest "myths" still in, say, almost everywhere, and seems to dominate the industry + its designs.
but the chlorophyl-molecule consists of a disc + tail, the latter being used to transfix it to a protein and arrange its spatial position inside the light-harvesting complex. which greatly changes its absorption spec and allowing other/higher stable excitation state(s).
then the core or antenna organize the placements of these chlorophyls to form an "electronic funnel" towards the trap - with surplus energy making it possible the exciton "travelling a longer way", better: being able to cross greater distances...jumping from & to the outer electron spheres.
It would surprise me if just blue+red resulting in best photosynthetis rates, I remember a study with blue, yellow & red to score highest.
let me just search on my desk for a pic
