How do the green buds go purple? Purple is actually the second most common color for cannabis and can be achieved easily by a seasoned breeder with a cursory knowledge of genetics.
The purple color usually appears upon maturation in strains that have the initial genetic ability to generate anthocyanin pigments. This substance is the main factor for coloration, however, without the needed conditions, the purple color might not even show.
The Hindu and Colombian Kush can easily develop anthocyanin pigments in the end of the production cycle. Certain environmental conditions must be met to get that purple color, such as low night temperatures. Another cannabis strain, known as Purple Orangutan, is the winner in colorization. This sort has some of the strongest tones of blue and purple.
