Here's another exapmple

#declare MyTexture =
   texture {
     pigment {
       marble
       color_map {
         [ 0.2 color rgb <1.0, 0.8, 0.0> ]
         [ 0.7 color rgb <1.0, 1.0, 1.0> ]
       }
       turbulence 0.7
       scale <1, 3, 1>/6
     }
     normal {
       marble 0.3
       turbulence 0.7
       scale <1, 3, 1>/6
     }
     finish {
       ambient 0.2
       specular 0.8
     }
   }

sphere {
   -y, 4
   texture { uv_mapping MyTexture }
}
