[pstricks] \multido and \newrgbcolor

[Philippe Charpentier]

Hi,
the following pstricks code

\multido{\n=0+0.012}{80}{\newrgbcolor{macouleur}{\n\space 0\space
\n}{\macouleur \Large Livre Math }}

was working with TeTeX-2.0.2, but with TeTeX-3.0 I get the following
error

! File ended while scaning use of \newrgbcolorx.

How I have to modify the code to get it working with the last package
pstricks?

Thank you very much in advance
