Class moderncv doesn't work with purple

Question

I've only recently started to work with LaTeX.
I've seen the nice CV that it is possible to do with moderncv, however I'm not able to change the color to purple. I do not understand why..
It works with other colors, blue, orange, etc..

\moderncvtheme[purple]{casual} 

Anyone has any idea how to change to purple or why this is happening?

MWE:

\documentclass[11pt,a4paper]{moderncv}

 % moderncv themes
\moderncvtheme[purple]{casual}
% character encoding
\usepackage[utf8]{inputenc}                   % replace by the encoding you are using
% adjust the page margins
\usepackage[scale=0.8]{geometry}
%\setlength{\hintscolumnwidth}{3cm}  

\firstname{First Name}
\familyname{Family Name}
\title{Curriculum Vitae} 

\begin{document}
\maketitle \\[-4.5em]

\section{Personal details}
\cvline{e-mail}{\small \\[-1.65em]
\cvline{mobile} {\small }\\[-1.65em]
 \cvline{nationality}{\small }\\[-1.65em]
\cvline{date of birth}{\small }\\[-2.5em]

\end{document}

Answer 1

The purple color option was added in version 0.13.0 of moderncv (released on November 06 2011).

Depending on what LaTeX distribution you are using (yes, I am looking at Ubuntu < 12.10...), you might still be using a very outdated version of moderncv. Please check your .log to find out if that is the cause of your issue, and update moderncv from ctan or launchpad accordingly.

Answer 2

Your given MWE works for me (after deleting your several \\[-1.65em]). If I change your line \moderncvtheme[purple]{casual} to \moderncvtheme[blue]{casual} the color in the documents changes.

I think your used pdf viewer does not show the changing of the color. I suggest you store a purple and a blue CV in two pdf files. Then use Acrobat Reader or SumatraPDF to view the CV and you will see the color changing. It could also be that you have to adjust your screen ...
