Which ones are primarily absorbed b carotenoids?

Violet and blue are primarily absorbed b carotenoids.
Carotenoids are essential compounds along with chlorophylls in photosynthetic bacteria, algae, and plants and are involved in photosynthesis and photoprotection.
Carotenoids harvest light energy and transfer this energy to chlorophylls through singlet-singlet excitation transfer.
Carotenoids also called tetraterpenoids, are yellow, orange, and red organic pigments that are produced by plants and algae, as well as several bacteria, and fungi.
