Defines a new colour that can be used in the document (RTF only). This command can also be spelt definecolor.
The first argument is the lower-case name of the colour, and the following three arguments specify the red, green and blue intensities, in the range 0 to 255.
The default colours are equivalent to the following definitions:
\definecolour{black}{0}{0}{0}
\definecolour{cyan}{0}{255}{255}
\definecolour{green}{0}{255}{0}
\definecolour{magenta}{255}{0}{255}
\definecolour{red}{255}{0}{0}
\definecolour{yellow}{255}{255}{0}
\definecolour{white}{255}{255}{255}
To use colours in a document, use the fcolfcol and bcolbcol commands.
Note that a document that defines its own colours should be converted twice within the same Tex2RTF session.
