Cool! Several minerals are green, like the emerald. It's due to the chromium content.
Not only that, but there are a lot of green-colored minerals too. You don't think about it as much, but they are there
Green was my favorite color as a kid, very common throughout the world OK, cool. That's the color between yellow and blue on the visible light spectrum. Its very vibrant and has many different shades In subtractive color systems, like painting, it's a combination of blue and yellow, but in the RGB model used for TVs, it's a primary color. Did you know that? Yep, it is very common in nature too Chlorophyll is actually the largest 'green' contributer in nature! Yea so nearly every plant has it which makes it so common Interesting, also a lot of creatures are green to make them less visible in their environment. Yea things like chameleons can adapt with it easily
