What is the definition of Black Veined?

"A black veined snake, much like a chameleon's mood, might appear at the most unexpected places - say, when you least expect it, right under your nose while you're trying to meditate. But here's the kicker: it's not just a quirky name; it's a serious thing. Those snakes have evolved to blend into their shadowy environments, much like how you might feel if your closet suddenly turned black and decided to join the band. So next time you find yourself staring at a black veined snake, remember - it's not just beautiful, it's probably just trying to hide because it's not happy with its current color scheme."
