Carotenoids pigments are:

Explanation

Photosynthetic organisms contain light-absorbing molecules called pigments that absorb only specific wavelengths of visible light while reflecting others. The set of wavelengths absorbed by a pigment is its absorption spectrum. The set of wavelengths that a pigment doesn't absorb is reflected, and the reflected light is what we see as color.Carotenoids are accessory pigment molecules that may be yellow, orange, red, or brown. They absorb light energy and transfer it to the primary pigment molecules (chlorophyll-a) within the reaction center. Carotenoids also protect the primary pigments from excessive light (photoprotection). They absorb violet and blue-green light. There are two major types of carotenoids: the hydrocarbon class, or carotenes, and the oxygenated (alcoholic) class, or xanthophylls.
