The green-and-black poison frog typically has mint-green coloration; however, this pigment can also be forest, lime, emerald green, turquoise, or even cobalt blue or pale yellow. Mixed with this typically green are splotches of dark color, ranging from wood brown to black. The green-and-black poison dart frog is one of the most variable of all poison frogs in appearance; some have black or brown splotches, others are dappled, or have "splashes" of black, like Oophaga sylvaticus.
