Would prepending 'current()' in front of 'idref' change the context
node from $colors/color back to the 'thing' node that it is
processing? I tried:

  <xsl:value-of select="concat('The @hex of that object means color ',

$colors/color[@hex=key('objects',current()/idref)/@hex],
                                ' (.)',$NL)"/>

To no avail. Probably because it doesn't address the second problem
you outline, but I'm not sure how to address that.

So the key is searching the the xsl document, while I want it to
search the input document? Is there a way to get it to search the
input document by using the $doc(key('objects',current()/idref) or
key('objects',current()/idref,$doc) constructs?

Thank you for your patience,
