Going along with what Shvrdavid says about needing a Map Ramp here is a picture of what ODF's setup above looks like with No Map Ramps, 1 and 2 Map Ramps.  This is something I have been working on for a slightly different project but was easy enough to convert for this use.

The left set goes from 0 to 100%.  The second set goes from 30% to 100%.  The third set uses 2 Map Ramps and goes from 30% to 50% in the range of 0 to 87 and from 50% to 100% in the range of 87 to 100.  Notice the outline in the ball and torus.  Just have a few bugs to work out and it will be posted to the Freebies section.
