[pstricks] colors

[Herbert Voss]

Hello all,

Uwe pointed me to an important fact of xcolor, the colorseries.
With this macro it is easy to use the colors by an index.
The color is set by "linecolor={name!![index]}". The braces are
not needed when using \psset

\definecolorseries{testA}{rgb}{last}{red}{blue}

\definecolorseries{testB}{rgb}{step}[rgb]{0.95,0.85,0.55}{0.17,0.47,0.37}
\resetcolorseries{testB}% defines a series of 16 colors (default)
