There are two ways.
Either in the parent template select only those items you do want to output, or in the child templates write templates to cover those you don't want to output.
Code:
<xsl:template match="Order">
<xsl:apply-templates select="Type | Color"/>
</xsl:template>
or
Code:
<xsl:template match="Order">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match ="Order/*[self::Type | self::Color]" priority="2">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match ="Order/*">
<!-- For all others do nothing -->
</xsl:template>
