We're here to help you sort through the mess with some nerdy tips about colors in marijuana, including where they come from, their purposes, and how they affect your stash.

Phytochemicals and color
Purple leaves aren't an indicator of strength, so what makes this color appear? A phytochemical (a biological compound in plants) called anthocyanin, a water-soluble flavonoid, appears in different hues depending on pH levels; it can fall anywhere on a spectrum of blue or purple, and occasionally red. Anthocyanins are prevalent in fruits and vegetables like plums, pomegranates, blueberries and eggplants.

Purple can also be provoked out of strains by causing chlorophyll deficiencies with temperature and other techniques.

Types of phytochemicals
The colors in each nug are dependent on strain genetics. Each strain's growth process triggers genes that connect to specific color ranges, meaning that each color we see has its own phytochemical:

• Anthocyanin - Blue/Purple
  
• Anthoxanthin - White/Cream
  
• Carotenoids - Yellow/Orange
  
• Chlorophyll - Green
  
• Lycopene - Red
  

When the plants feel it's harvest time, nature invokes the change, allowing marijuana flowers to mature into color like autumn leaves until they're ready to be plucked. This is when each phytochemical blooms, showing us the full-color spectrum of what each strain has to offer.

Pistils are for girls
Pistils, those tiny hairs that cover buds, are more important than you might have thought. Pistils are pollen-catching hairs that pop out of the calyx during the plant's vegetative stage. They're ghost-white until the plant reaches its flowering stage. At that time, their priorities switch from sprouting to pollen-catching; that pollen either births seeds or aids bud growth. Once the nugs are fattened, the pistils are done vacuuming pollen and fizzle out into various colors from fire-red to tan or burnt orange.

Fun fact: Pistils are often referred to as cannabis vaginas, as they are the bud's sexual organ. They contain ovaries, birth pollinated seeds and even have their own form of menopause once they're beyond maturity.

There are antioxidants in phytochemicals
While phytochemicals and pistils are essential to each nug, they aren't indicators of THC content. Pistils have a place in the maturation process of each bud but produce no cannabinoids or other psychoactive factors. Phytochemicals in fruits and veggies affect color, taste and smell, but they affect only color in cannabis.

Some scientists believe there is a link between phytochemicals that provide antioxidants and health benefits from ingesting cabbage, raspberries and red onions and the phytochemicals that spark color changes in cannabis — but more research is required to confirm these claims.
