In this case, the buds are purple, but the pistils are orange. To maximize the final color, you want to choose a strain with brightly colored buds and pistils. For example, this bud has purple calyxes, mostly purple pistils and even some purple leaves.

This combination makes the entire bud appear bright purple. Choose Deep Purple Buds for Maximum Color After Drying/Curing – Deeply colored buds (sometimes called “black” strains) tend to be the most vibrant after drying/curing. To produce the most colorful buds, you need to make sure the color goes all the way through the buds, and ideally, also through all the surrounding leaves. This level of color-penetration is most likely to happen with intensely dark colored buds. Buds that are paler in color tend to lose a lot of their vibrancy in the post-harvest processing. These buds were mostly pink at harvest, but the color doesn’t go all the way through the buds. There was still a lot of green on the parts of the buds that didn’t get direct light. After they’re trimmed and dried, the pink color has become more subtle. You will “keep” the most color after drying/curing by choosing strains that are dark purple through and through, from buds to pistils to leaves if at all possible. Deeply colored buds keep more of their color after drying and curing than pale purple or pink buds.

These buds were deep purple at harvest… When buds are darkly colored, they tend to keep more color after being dried and trimmed. Note: Your buds will naturally lose some of their overall vibrancy and color during the drying/curing process (but not any of their potency!). That’s why you will likely never run into neon purple buds that have already been dried and cured for 2+ weeks. Even green buds go from being bright green to a more muted green color by the time they’ve cured for a few weeks. When you see very brightly colored buds, it almost always means the buds are still relatively fresh. Although color is determined primarily by genetics, there are a few things you can do to help your plant express its natural colors… Temperature – Some Strains Express Colors When the Night Temperature is a Few Degrees Cooler than the Day. If you’re growing a strain that turns color, some strains will only show their colors when night temperatures are at least a few degrees cooler than during the day in the flowering stage, especially towards the end. However, some plants don’t react to cool night temperatures, and many strains (like Panama) nearly always turn color no matter what the temperature. Certain strains like Querkle turn color more easily when the temperature is warm during the day as opposed to cool at night. So, it’s always a good idea to aim for nice warm days, and cool, comfortable nights, because that contrast seems to help bring out colors for many strains. Warm Days (75-80°F / 24-27°C) Cool Comfortable Nights (65-70°F / 18-21°C) Note: Some strains turn color no matter what the temperature. You can sometimes contact the breeder and ask if they have advice on how to bring out colors for a particular strain. I’ve found that most breeders will get back to you quickly if you go to their website and ask questions! Some strains need contrast between day/night temperatures for their buds to turn colors. For example, the buds of this Auto Frisian Dew turned bright purple after it started getting below 70°F (21°C) temperatures at night. In some cases, a plant may produce purple tones in response to intense, direct light (on buds and leaves). Although we’re not sure exactly why it’s possible this may act as a sort of sunscreen for the plant! The importance of light levels varies on a strain by strain basis. The pH at the Roots may affect cannabis bud color expression. Outside the cannabis world, there are a few species of plants with flowers that are known to turn different colors based on the pH at the roots. For example, the flowers of specific types of hydrangeas can turn blue in very acidic soil but may turn pink if exposed to neutral or only slightly acidic soil (though this type of variation is rare in the plant world). Yet there have been occasional reports of cannabis strains that produce different bud colors based on the pH at the roots, though unfortunately, more testing is needed! If growing multiple plants of the same strain, you might consider giving plants different pH ranges to see what effect it has on the final bud color! Here are some pictures of cannabis strains that sometimes grow colorful purple and pink buds. The next two pics are of the strain Frisian Dew, a popular strain by Dutch Passion, who specifically designed the strain for growing outdoors. It is exceptionally hardy, high yielding, and is also mold and pest resistant.

About 50% of the time, Frisian Dew buds will turn bright purple instead of green! The plant in the middle with the dark purple buds is Frisian Dew. Purple Trainwreck buds are usually purple-tinted, with purple leaves or pistils. This Purple Trainwreck plant is growing purple pistils. For this Purple Trainwreck cola, it’s mostly just the leaves turning purple. This Purple Trainwreck bud turned particularly purple. The following plants with pink pistils are from the strain Panama by Ace Seeds.

This is what Panama buds may look like when they’re first growing in. As the Panama buds develop, the pistils and even the buds themselves may intensify their pink color. Smooth Smoke buds (by Tropical Seeds) can become quite colorful, with colors from hints of pink to deep purple!
