I am trying to use pstricks with beamer. However everytime I get an error message saying

Package xcolor error undefined color model

I have googled it and tried different solutions but none worked!




*I was trying to copy paste a pstrick format diagram from jpicedt here.*

    Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – user13907 Jun 4 '13 at 13:17
  • It does not work. It compiles if I do not use the pstricks package. Mine is 2.8. 2.9 did not compile. – Bhavish Suarez Jun 4 '13 at 13:48
  • Are you compiling with latex or pdflatex? – Werner Jun 4 '13 at 14:06
  • With latex. pdflatex does not work with pstricks rights? – Bhavish Suarez Jun 4 '13 at 14:15

You loading the package xcolor with the pstricks package. You have to give xcolor some arguments. So try two possible solutions instead of\usepackage{pstricks}




a little more information, but sorry in german http://www.mrunix.de/forums/showthread.php?t=58721

  • I have tried it, I get > Latex error: option clash for package xcolor – Bhavish Suarez Jun 4 '13 at 14:11
  • I have tried different arguments, involving pst for xcolor. Nothing worked. – Bhavish Suarez Jun 4 '13 at 14:11

use before \documentclass{...}


Your example gives with a \listfiles at first line (list at the end of the log file):

  • It does not work either. Is there any other way of inputting flowcharts or other diagrams? – Bhavish Suarez Jun 4 '13 at 14:30
  • It does not work either it not a helpful error message. I have no problem with your example when I correct the two errors. – user2478 Jun 4 '13 at 14:35
  • I got the error message which I had first obtained. Package xcolor error, undefined color model. I've tried various suggestions but nothing works. – Bhavish Suarez Jun 4 '13 at 16:33
  • And how is the undefined color model called? Post the complete error message. – user2478 Jun 4 '13 at 16:42
  • It's the complete message. There's no colour model mentioned there. – Bhavish Suarez Jun 5 '13 at 10:05
