Look for the interpolate function then:
http://docs.geoserver.org/latest/en/user/styling/sld-tipstricks/transformation-func.html#interpolate
It has a gotcha though, the GetLegendGraphics code does not recognize it,
so you won't get a nice legend out of it (assuming
you even need to call onto GetLegendGraphics, that is).
