Carotenoid Yellows Oranges

Carotenoid yellows and oranges represent a family of pigments produced alongside chlorophyll in cannabis plant tissues, responsible for golden, amber, and orange coloration in leaves, bracts, and pistils. These compounds—including β-carotene, lycopene, and xanthophyll—accumulate as chlorophyll breaks down during flowering and senescence, becoming visually prominent in late-stage phenotypes. Carotenoid expression is influenced by genetics, temperature fluctuations, nutrient availability, and light spectrum, making this trait variable even within stable cultivar lines. Breeders and cultivators document carotenoid intensity as a secondary marker for plant maturity and phenotypic consistency. This pigment family is distinct from anthocyanin reds and purples, and does not indicate cannabinoid or terpene content.

Breeders select for carotenoid expression as a visual marker of phenotypic stability and environmental response, particularly when developing cultivars for aesthetic consistency in commercial and specialty markets. Carotenoid intensity can serve as a secondary indicator of harvest timing and post-senescence plant chemistry, though direct correlation with cannabinoid maturity remains cultivar-depen
