Color Polymorphism
Color polymorphism in cannabis refers to the genetic capacity of plants to express multiple distinct phenotypic colors—such as purples, reds, blues, and deep greens—across different individuals of the same strain or even within single plants. This variation arises from interactions between anthocyanin and carotenoid pigments, environmental conditions (particularly cool temperatures), and underlying genetic loci that regulate pigment expression. Lineage records frequently report color polymorphism in families descended from Afghani, Thai, and North American landrace genetics, where phenotypic diversity was historically preserved through open pollination. Modern breeders recognize color polymorphism as a stable, heritable trait that can be selected and stabilized across generations, distinct from temporary color changes caused by stress or nutrient deficiency.

Breeders working with color polymorphism systematically select parent plants exhibiting consistent color expression to establish stable color-variant lines within a strain family. Understanding the genetic architecture of pigment production allows breeders to maintain or amplify color diversity while preserving other desirable agronomic traits.
