Black mambas are actually brown in color. They get their name from the blue-black of the inside of their mouths, which they display when threatened.
The black mamba has either a dark olive, olive green, grey brown or metal color skin depending on what area on the country the Black Mamba is found. As Black Mamba’s begin to age, their skin starts to become darker.
The green mamba may bear a variety of colors, ranging from greenish-yellow, olive green, emerald green to sky blue or yellow. Its long tail has yellow scales, which are edged in black.
