Well, upon a quick somewhat inebriated research session, I found that gd2
has the capability to find the color of a pixel
(http://us2.php.net/manual/en/function.imagecolorat.php), which tells me
that you could probably write something in php to 'parse' an image for the
majority color with gd2.  Then again I tend to avoid gd due to how slow it
can be with php, but if gd does it, I'd imagine the functionality being
available with imagemagick and/or pnm. So, I suppose it's possible with php,
although probably slower than an 'outside' solution.
