Seasonal Color Shift
Seasonal color shift refers to the natural phenotypic expression where cannabis plants display distinct color changes—often purples, reds, blues, or yellows—in response to temperature fluctuations during late flowering. This trait is commonly associated with anthocyanin and carotenoid pigment production triggered by cooler nights, particularly below 60°F (15°C). While UV exposure and genetic predisposition also influence coloration, temperature remains the primary environmental driver. Lineage records frequently report color-shifting traits in indica-dominant and hash-plant derived families, though the mechanism remains largely dependent on individual plant genetics and cultivation conditions. Documentation of this trait in breeding programs helps predictability, though expression is not guaranteed under all environmental scenarios.

Breeders working in this category select for genetic stability and consistent pigment production to develop commercially predictable color phenotypes. Color shift is often combined with other traits like terpenoid profiles and plant structure to create distinct visual cultivar markers without relying on secondary effects.
