Better instructions
== The basics ==
Colors are defined as vectors with three components: a red, green and blue one. Like pens, colors have their a {{code|with...}} command:
withcolor (.4,.5.,6)
</pre>
The settings will be in {{code|tex/texmf/web2c/texmf.cnf}} or {{code|tex/texmf-context/web2c/context.cnf}} inside your ConTeXt tree. If you are using ConTeXt from the Debian/Ubuntu distribution of TeX, instead of via the recommended [[ConTeXt Standalone]], you need to edit ''/etc/texmf/texmf.d/95NonPath.cnf'':, instead. The part you need to edit will look something like this.
<pre>
* Comment out the .mpost line (MetaFun uses the main_memory value of 1000000; the difference in values is the cause of the problem).
* Regenerate {{code|/etc/texmf/texmf.cnf}} (If you are not using the standalone, regenerate your TeX with {{code|sudo update-texmf}}; )* then Lastly, regenerate the MetaFun format with {{code|texexec --make metafun}}* transparency . Transparency should work now.
