Carotenoids. The colors of the carotenoids are familiar as the fall colors of leaves. As the leaves lose their chlorophyll, the more persistent carotenoids give the pleasant reds, yellows and oranges of the autumn foliage.Beta-carotene is the most important of the carotenoids. Lycopene, the color of tomatoes, is also a carotenoid.his chlorophyll resides mostly in the chloroplasts and gives leaves their green color. The range of light absorption in leaves is extended by some accessory pigments such as the carotenoids, but does not cover the entire visible range-that would make the leaves black!
