Explanation:

The statement string color = "blue" is an assignment statement.

The syntax of an assignment is

Variable = Value

The expression or the value on the right hand side in the statement above is a string literal or string constant.

The Variable it is being assigned to color is the string reference (on the left hand side). It is called the string reference because the value "blue" is of string data type.
