The green-and-black poison dart frog is one of the most variable of all poison frogs in color and pattern. This variation is to some extent individual, but also depends heavily on the exact location. Despite the name green-and-black poison dart frog, some variants have no green or no black; a few, like the brown and cream-white Campana variant, may have neither green nor black. However, most often, green-and-black poison dart frogs have a highly variable, spotted or banded pattern in vivid mint-green coloration, but this can also be a darker green, forest-green, lime, emerald, turquoise, or even blue, whitish or pale yellow. Mixed with this are splotches of dark or dull coloring, most often blackish, but ranging from whitish-brown and bronzy brown to dark brown and pure black. The amount of dark or dull coloring varies greatly (certain variants are entirely black, or dark with only a few small green spots or streaks) and may appear as large or small spots or blotches, or as a dappled or "splashed" pattern.
