Set global text color?

I know that to use color in a document you have to load the package "color". But I can only find documentation on how to define color for a given part of the document... not what I want to do. What I do want is to define a global text color, that is used per defau开发者_如何学Pythonlt.

Is this possible? Can anyone tell me how to do this?

If you use, for example

\color{red}

in your preamble, before \begin{document}, then the text should be red throughout your document unless you override with another \color declaration.
