I thought you have a the color value itself as the attribute.
But if you'd categorize by a different value you might want to define a
different class for each value, something like
LAYER
CLASS
EXPRESSION ([MYCOLORATTRIBUTE]=1)
STYLE
COLOR 255 255 0
END
END
CLASS
EXPRESSION ([MYCOLORATTRIBUTE]=2)
STYLE
COLOR 255 0 0
END
END
END
