Ever gazed upon a stunning cannabis nug shimmering with shades of deep purple, amethyst, or even nearly black, and wondered what gives it that regal appearance? It's not just a pretty face! That vibrant coloration is often thanks to a group of pigments called anthocyanins, the very same compounds that give blueberries, red cabbage, and eggplants their rich, jewel-toned hues. These pigments are actually a plant's natural sunscreens, protecting it from UV damage and other environmental stressors. While genetics play a starring role in whether a plant has the *potential* to produce these colors, environmental factors like cooler nighttime temperatures (especially as summer evenings start to gently cool down) can often coax these stunning purples to truly shine through. So, the next time you encounter a truly magnificent purple strain, remember you're not just admiring a beautiful bud, but a botanical masterpiece showcasing nature's own vibrant palette!
