Without more information, its hard to tell exactly what kind of a snake this might be. It is most likely a garter snake, which is a beneficial snake that lives in many parts of the United States.
The Black Mamba is an extremely fast, extremely poisonous snake.
However, the Black Mamba is so named because the inside of its mouth is black; when threatened, it will gape, displaying the black inside of its mouth as a threat or warning (similar to the North American Cottonmouth, which displays the white inside its mouth). The Mamba's skin is actually a pale-to-medium gray. It is found in the wild in Africa, and, in addition to being very fast and very venomous, it can grow to be very large.
most snakes are dangerous, especially if you don't know if they're poisonous or not. stay away from any suspicious snakes. most snakes are more afraid of you, than you of them. but still stay away from ALL snakes.
They are non Venomous snakes

It depends on the snake. They can be blue, to brown, to black, to red. They can be solid or have very complex patterns. You should post a more specific question if you're asking about a certain type of snake.

it is brown or black
Many, many snakes are brown and black, as this coloration is useful for camouflage. The answer to this question also depends on what you would consider a "stripe". The ball python is a fairly common pet snake that has brown and black markings. As do some color strains of corn snakes and garter snakes. The rat snake can be brown with black stripes, but I've never seen one with the reverse. The black-striped snake is so named because, go figure, it is black and striped. Its stripes are brown. Indigo snakes are almost entirely black, but can have brownish markings around their head and chin. The mud snake and crayfish snake are black with a brown belly which can, from the side, look like a single brown stripe stretching the entire length of the snake. The hognose is also black and brown, though again it's more brown with black stripes than black with brown stripes. The night snake can have wither brown stripes or black stripes, but not both. The common kingsnake and the plainbelly water snakes are actually brown with large, black spots, but if you only look quickly they can appear black with many thin, brown stripes. Most other water snakes also have brown and black markings. The whipsnake is a gray with brown stripes. The longnose snake and mountain patchnose snake are black with brown stripes. As is the Western Ribbon snake, though it can also have red stripes in the mix. The copperhead and rattlesnake can also both have black and brown markings, that in some cases will certainly appear mostly black with brown stripes. This is not, by any means, a complete list of snakes that fit the description you gave. If you could post a picture you would, I'm sure, get a more helpful response.
I believe you are referring to the Grey Rat Snake.
