Different Colors of Cannabis

Color isn’t just a cosmetic feature of cannabis—it’s a clue. From deep greens to rich purples, the pigments in your flower may reveal information about its genetics, flavor, and even how it might make you feel. In this guide, we’ll break down what causes cannabis to take on different hues, whether those colors influence effects, and why dark weed strains like Purple Punch are so highly sought after.

Why Does Cannabis Come in So Many Colors?

Dark weed strains are becoming more popular. If you’ve ever wondered why cannabis plants have different looks and effects, genetics are the reason why. Learn more about how different cannabis strain types influence appearance, effects, and cultivation. Leafly explains that pigments like anthocyanins are responsible for the purple, blue, and red hues in some cannabis strains, with environmental factors like temperature and pH playing a key role.

Sativa and indica plants evolved in separate regions of the world, developing unique, distinct characteristics to survive — and thrive — in those climates. Their unique coloration can be linked to how these plants express pigments under environmental stress, especially colder climates for indicas as described by Leafly.

What’s the best way to distinguish between indica and sativa cannabis strains? Look at the buds. Sativas originate in warm, tropical climates, which encourage brightly colored flowers. With cold temperatures encouraging deeper colors, such as those found in dark weed strains, many indica strains are often darker than their sativa counterparts.

Can You Taste the Colors?

Here’s a fun fact: The colors on your cannabis result from the anthocyanins, a subclass of flavonoids that the plant produces and appear red, orange, purple or blue, depending on their pH. ACS Laboratory explains how flavonoids (like cannflavins) influence flavor and may offer anti-inflammatory effects. Temperature and light cycle also play vital roles in cannabis coloring.

The color of your cannabis flowers is often a function of the genetics of the plant and the terpene profile. A plant’s response to specific stress can cause the plant to produce a large amount of anthocyanin, which absorbs blue and green light wavelengths, creating vibrant purple hues on the plant. These pigments are also found in foods like blueberries and red cabbage, known for their antioxidant properties. Healthline notes that anthocyanins may reduce inflammation and support cardiovascular health.

With genetics and environmental impacts altering the color of cannabis, different shades can come with disparate effects, taste and even smell.

Real Talk: Why Your Purple Bud Might Not Look Purple

Not every nug in your jar will be a deep violet masterpiece—and that’s okay. Even within the same strain, buds can vary in color based on where they grew on the plant. Top colas get more light, while lower buds stay shaded, which can change how purple shows up.

Some buds are so frosty with trichomes, the purple is hiding underneath. Others might have just a subtle tint. That’s the beauty of cannabis: no two buds are exactly the same, and every bag is a little surprise.

What Are the Benefits of Dark Strains of Weed?

A lot of people think color means strength, but (contrary to popular belief) the color of a cannabis flower doesn’t indicate its potency. Veriheal confirms that while purple buds are eye-catching, they’re not necessarily stronger than green ones. While anthocyanins don’t change THC levels, plants producing an increased amount of these powerful antioxidants can deliver additional health and stress relief benefits.

Dark weed strains typically have a much deeper and rich flavor due to the increased amount of anthocyanins. This flavor complexity is part of what’s referred to as the entourage effect, in which flavonoids like anthocyanins work synergistically with terpenes and cannabinoids. Leafwell breaks this down.

Green is the primary color of most flowering plants, including cannabis, due to chlorophyll, which gives plants a green pigmentation. Dark green weed strains generally have more of this pigment than others.

Ranging in color from deep purple with almost no green to next to no purple at all, dark purple weed strains are an excellent source of anthocyanins, which are proven to have anti-inflammatory and neuroprotective benefits.

Anthocyanins help create a rich and delicious flavor signature of dark weed strains such as Purple Kush or Sour Diesel. While these flavonoids don’t change how much THC a flower has, they give these strains their rich taste and distinct colors.

Recent research even identified cyanidin-3-rutinoside as a key pigment in purple cannabis, linking genetics and stress response to coloration. You can read the full study here on NIH.

FAQ: Cannabis Colors & Strain Effects

Q: What causes cannabis to turn purple?
A: Anthocyanins—natural pigments also found in blueberries and eggplant—become more prominent in cannabis when exposed to cooler temperatures and pH changes. These are responsible for the purple, red, and blue hues in certain strains.

Q: Is purple weed stronger?
A: Not necessarily. THC content determines potency, not color. While purple strains are beautiful and flavorful, their color doesn’t guarantee a stronger high.

Q: What do different weed colors mean?
A: Color can indicate the presence of specific flavonoids or pigments, but it doesn’t directly correlate with effects. However, it can hint at flavor profiles and terpene expressions.

Q: Do different colors taste different?
A: Yes. Dark strains often have richer, deeper flavors due to higher flavonoid content, while green strains can be lighter and fresher depending on their terpene mix.

Q: Are colorful strains better for you?
A: Colorful strains may contain more antioxidants like anthocyanins, but their health benefits are still being studied. Their unique visual and flavor appeal adds to the overall experience.
