Pigment Chemistry

Pigment chemistry in cannabis refers to the molecular compounds responsible for the plant's visible coloration—primarily anthocyanins, carotenoids, and chlorophyll. These pigments are synthesized through genetic pathways and respond to environmental triggers like temperature, light spectrum, and soil pH. Breeders study pigment expression to understand genetic inheritance patterns and select for stable color traits across generations. Pigment chemistry is largely distinct from cannabinoid or terpene pathways, though all three classes of compounds contribute to the plant's overall phenotype. Documentation of pigment genetics remains less standardized than cannabinoid research, making lineage records particularly valuable for breeders working in colored-cannabis development.

Breeders use pigment chemistry as a visual marker for genetic stability and can select parent plants displaying consistent anthocyanin or carotenoid expression. Understanding pigment pathways helps predict how environmental conditions will influence offspring appearance, supporting reproducibility in commercial cultivation.
