Beth -

You can adjust the argument of Hue to reduce its range using a pure function.

     ColorFunction -> Hue  can be written ColorFunction -> (Hue[#]&)

if you multipy the argument of Hue by say .9 you, in effect reduce it's range

      ColorFunction -> (Hue[.9 #]&) will color your minimum values red and
your max value a pinkish/purplish/rose.

The parentheses in the examples above are important.  You can try other
operations on the argument of Hue.  One restriction is that your result
must
be in the {0,1} range.
