Not sure what your context is...  You canbt put the || in an XPath, but
if youbre in some procedural language like Perl or Java, then yes.
Pseudocode:

color_label = select( "//text[@id='color' and lang('en-us')]" ) ||
              select( "//text[@id='color' and lang('en')]" ) ||
              select( "//text[@id='color']" )

That would (presuming normal behavior of logical or) get the best match
for you.
