Light Stress Pigmentation
Light stress pigmentation refers to anthocyanin and carotenoid production triggered by high-intensity light exposure during flowering, resulting in purple, red, or orange coloration in cannabis tissues. This is a physiological response distinct from genetic predisposition to color expression. Environmental factors—particularly UV exposure and cool temperatures combined with intense light—commonly intensify these pigment compounds. Breeders distinguish between genetically-determined color traits and environmentally-induced stress pigmentation when selecting parent plants. Understanding this mechanism helps cultivators and breeders differentiate phenotypic expression from stable genetic markers in breeding programs.

Breeders working in ornamental and specialty genetics note light stress pigmentation as an environmental modifier rather than a stable breeding target. Documenting which genetic lines express secondary pigments under controlled light stress helps inform selection strategies for consistent color expression across growing conditions.
