Color Phenotypes

Color phenotypes in cannabis refer to the visible pigmentation expressed in plant tissues—leaves, bracts, flowers, and sometimes stems—resulting from anthocyanin, carotenoid, and chlorophyll interactions. These traits are inherited through polygenic and environmental factors, including temperature, light spectrum, and nutrient availability during flowering. Breeders document color expression to preserve aesthetic markers, support strain identification, and maintain genetic consistency across generations. Common phenotypes range from deep purples and blues to reds, oranges, and yellows, often influenced by recessive alleles and environmental stress during late flower. Color phenotypes carry no established correlation with cannabinoid or terpene profiles, though lineage records frequently associate certain color expressions with specific parent genetics. Understanding and stabilizing color

Breeders select for stable color phenotypes through multi-generational testing to create consistent visual markers within seed lines and clonal populations. Color stability serves as a practical phenotypic indicator for pheno-hunting, seed production tracking, and maintaining genetic fidelity in commercial and artisanal breeding programs.
