if it has a diamond shape head it is poisonous
what does a white snake with black diamonds on the back mean
That is the endangered Georgia Tube snake.

Lots of snakes are brown and black. You'd need to be more specific about the patterning, size, head shape, and location you spotted the snake to get a good answer.
Are you saying that the snake has like a "hood" around the head? If so, that is a cobra.
king cobra
black snake
A black snake with yellow markings typically has a dark black body with distinct yellow patterns or stripes. These markings can vary in shape and size, but they are usually vibrant and easily noticeable against the snake's dark coloration.
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.
