Conditional Formatting Rules

adamboscoucdenver  sounds like you want a full rainbow of color.  I don't believe that is possible (would love to hear someone correct me because that would be really interesting).  That said, I assume you are already using 3-Color Scale for each range, because otherwise you might get similar results by using that instead of 2 2-color ranges.  The 2 other options for you are then using a lot of custom formula based conditional formatting (ugh even thinking of that) or a custom VBA function that basically does a custom conditional formatting.
