This needs to be done in the code unfortunately. Edit Webmail.pm around line 512:

$out .= &Webmail::page('msg-row.htm', $IN, $USER, { template => $USER->{'template'}, msg_size => $size, sb => $in->{sb}, so => $in->{so}, nh => $tr, p => $in->{nh}, tb => $in->{tb} }, $msg_r );

and add into that list:

, bgcolor => $bgcolor

and just before that do:

$bgcolor = ($bgcolor eq '#FFFFFF') ? '#000000' : '#FFFFFF';

using whatever two colors you want. Then you can use <%bgcolor%> in your msg-row template.

Cheers,

Alex
