Where are they defined ?...

In the PSTricks user's guide, by T. Van Zandt, you can read:

"The grayscales black, darkgray, gray, lightgray, and white and the
colors red, green, blue, cyan, magenta, and yellow are predefined in
PSTricks."

The file pstricks.tex contains :

\newgray{black}{0}
\newgray{darkgray}{.25}
\newgray{gray}{.5}
\newgray{lightgray}{.75}
\newgray{white}{1}
\newrgbcolor{red}{1 0 0}
\newrgbcolor{green}{0 1 0}
\newrgbcolor{blue}{0 0 1}
\newrgbcolor{yellow}{1 1 0}
\newrgbcolor{cyan}{0 1 1}
\newrgbcolor{magenta}{1 0 1}

You have to define your own pink :

\newrgbcolor{pink}{1 .6 .8}

You can put this line in the file pstricks.con, a configuration file
read after pstricks.tex : you have to uncomment the \pstcustomize
command, and you can write \newrgbcolor{pink}{1 .6 .8} and other colors
after.


Now, how do you draw a panther with PSTricks?...
