I recently noticed the following in the NEWS file for gnuplot (from
the CVS archive):

  News, changes and fixes since gnuplot version 4.0
  =================================================
  [...]
  * NEW 3D plots can read RGB color triples as part of input data
  * NEW linetype colors via "lt {palette {frac <val> | cb <val>}}"
  * NEW linetype colors via "lt {rgbcolor {"name" | "#RRGGBB"}}"
  * NEW palette and rgb linetype colors apply to all 2D and 3D plot elements
