The colors of cannabis flower, such as purple or orange hues, are primarily due to pigments called anthocyanin's and carotenoids. Anthocyanin's are responsible for producing purple, blue, and red colors in plants. They are particularly sensitive to changes in pH, temperature, and light exposure. Genetics play a significant role in determining whether a particular strain will produce anthocyanin's. Stress factors like cooler temperatures during the flowering stage can also trigger the production of anthocyanin's, resulting in purple hues on the flower.
Carotenoids are pigments producing yellow and orange colors in plants. Carotenoids are always present in cannabis. Their visibility can vary depending on factors like genetics, environmental conditions, and nutrient availability. Carotenoids contribute to the overall health and vitality of the plant, and they may also have some influence on the flavor and aroma profile of the harvested flowers.
The specific combination and concentration of these pigments, along with other factors such as terpene profiles and cannabinoid content, contribute to the overall appearance, aroma, and effects of different cannabis strains. Ultimately, whether you prefer purple or orange cannabis depends on your personal taste preferences, desired effects, and therapeutic needs.
