Let’s dive in.

What gives some cannabis plants their dark coloration?

The color of cannabis plants depends on a few factors.

The primary reason is due to the presence of flavonoid phytochemicals called anthocyanins. These compounds produce red, blue, purple, or pink buds.

There are over 500 anthocyanins, each resulting in a wide range of hues. Here are the primary ones, along with the colors they produce:

  • Pelargonidin: Produces orange hues, depending on pH levels.
  • Malvidin: Shows up as purple, red, or blue weed, depending on pH levels.
  • Delphinidin: Creates pink or reddish nugs in acidic conditions, sometimes appearing blue in rare circumstances.
  • Cyanidin: Shows purple or red hues when the hydrogen concentration is under 3.0. The colors turn blue if the pH is above 8.0.
  • Peonidin: One of the most stable anthocyanins. Creates deep blue when the pH is high and neon red when it’s low.
  • Petunidin: Results in dark purple and red shades.

The primary job of anthocyanins is to protect marijuana plants from harmful UV rays and pathogens. They also act as an antifreeze, which prevents the crops from becoming too cold.

If you notice brown-colored weed, there could be an issue with your crops’ growing conditions. Cannabis plants lose color and start to fade when there aren’t enough nutrients, which signifies the buds may be dying.

Besides anthocyanins, what else causes different pigmentation in cannabis crops? Genetics and environmental factors also play a large part in the plants’ hues.


Black cannabis is often a result of genetics. Cultivators find strains with high concentrations of anthocyanins and breed them with similar variants to preserve the dark hues in future generations.

Find ebony strains by choosing a cultivar with “black” in the name or one with a recessive phenotype. The primary reason breeders create marijuana plants with this color is for the appeal of the gorgeous buds.

Environmental factors

Besides genetics, the most significant factor that influences color is the pH balance. Cannabis crops generally prefer soil with acidic conditions. In these cases, the buds create red or orange strains. If the earth is neutral, more blue-like shades appear.

  • Soil pH: High pH levels result in deep plum colors, often resembling black. Keep the pH balance at 5.8–6.8 for these dark purple strains.
  • Temperature: Colder climates affect the hue of your marijuana buds. When the temperatures drop, the plant produces less chlorophyll, the compound that provides green pigments. Cool conditions result in more anthocyanins, creating black strains.

What parts of a weed plant can turn black?

Anthocyanins exist throughout your cannabis crops’ anatomy. The plants can turn dark on every surface, from the stems to the leaves and buds.

In most cases, the hairs on marijuana buds are typically brown or orange. The trichomes remain silky, being brighter in white cultivars.

Black weed characteristics

Pigmentation doesn’t affect the potency of weed buds. You may notice a pattern amongst ebony nugs due to breeders creating strains with specific, often recurring, genetics.


Some users report that black weed strains have elevated psychedelic effects and higher THC levels, but it depends on the genetics. Darker variants are mostly associated with indica genetics, though you may also find sativa varieties with ebony pigmentation.

Taste and aroma

Black cannabis cultivars tend to have fruity, berry flavors and fragrances. When looking at existing ebony variants, most have sweet, spicy, nutty, and earthy scents and tastes.

Tips for black cannabis

If you notice your cannabis crop going black without any changes to the conditions, take action immediately. Always ensure an ideal environment for your plants to avoid lasting damage.
