For recent versions of moderncv you need to use
\usepackage{etoolbox}
\patchcmd{\makecvtitle}{\color{color2!50}\@firstname}{\color{color2}\@firstname}{}{}
\patchcmd{\makecvtitle}{\color{color2}\@lastname}{\color{color2!50}\@lastname}{}{}
(Thank you, Gonzalo Medina!)
The following applies only for version 2008/06/17 v0.7 of moderncv
The names are typeset by the commands
\firstnamestyle
\familynamestyle
which are defined in moderncv.cls as follows
\providecommand*{\firstnamestyle}[1]{{\firstnamefont\color{firstnamecolor}#1}}
\providecommand*{\familynamestyle}[1]{{\familynamefont\color{familynamecolor}#1}}
You can adjust them to your liking via
\renewcommand*{\firstnamestyle}[1]{{<whatever>#1}}
\renewcommand*{\familynamestyle}[1]{{<whatever>#1}}
If you just want to switch the colors, your call would be
\providecommand*{\firstnamestyle}[1]{{\firstnamefont\color{familynamecolor}#1}}
\providecommand*{\familynamestyle}[1]{{\familynamefont\color{firstnamecolor}#1}}
