No.

You can declare a new variable like this:

<xsl:param name="color">123456</xsl:param>
<xsl:variable name="color2">
   <xsl:choose>
      <xsl:when test="ancestor::top_bar">ffffff</xsl:when>
      <xsl:when test="ancestor::bottom_bar">000000</xsl:when>
      <xsl:otherwise><xsl:value-of select="$color" /></xsl:otherwise>
   </xsl:choose>
</xsl:variable>

Now $color2 contains the value you want.
Hope that helps,
Oliver
