Following is a XSLT 2.0 solution..
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="2.0">
<xsl:output method="text" />
<xsl:template match="/data">
<xsl:variable name="temp1" select="colors/color" />
<xsl:for-each select="pictures/picture">
<xsl:variable name="temp2"
select="distinct-values(color)" />
<xsl:if
test="count(distinct-values($temp1[.=$temp2])) >
1">
picture sample #<xsl:value-of select="@sample"
/><xsl:text>
</xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
The expression distinct-values($temp1[.=$temp2]) finds
the intersection of sequences $temp1 and $temp2.
XSLT processor used: Saxon 8.3 ..

Okay,
Lets say you have a set of colors and you have a
whole bunch of
pictures and you want to match on all pictures who
have one or more of
the given colors but you have to at least match on 2
of them (unique,
so not red and red - so a picture could list red
twice but that would
not be a match). I'm trying to use keys and
grouping to solve this
but thinking that I might be making this more
difficult. At any rate,
I'm stuck and would appreciate some help : )
Sample Data (expected results below):
<data>
<colors>
<color>red</color>
<color>blue</color>
<color>fucia</color>
<color>violet</color>
</colors>
<pictures>
<picture sample="1">
<color>black</color>
<color>grey</color>
<color>white</color>
</picture>
<picture sample="2">
<color>red</color>
<color>green</color>
<color>brown</color>
<color>blue</color>
</picture>
<picture sample="3">
<color>purple</color>
<color>orange</color>
</picture>
<picture sample="4">
<color>blue</color>
<color>green</color>
<color>red</color>
</picture>
<picture sample="5">
<color>fucia</color>
<color>green</color>
<color>violet</color>
</picture>
<picture sample="6">
<color>red</color>
<color>brown</color>
<color>red</color>
</picture>
</pictures>
</data>
Expected Results (picture matches based on 2 or more
colors used and
listed in colors above)
picture sample #2
picture sample #4
picture sample #5
