You can even make it a function of the parameter if you wish. Here are a couple of examples: In[9]:= ParametricPlot3D[ {Sin[t], Cos[t], t/3, RGBColor[1,0,0]}, {t,0,15}] Out[9]= -Graphics3D- In[10]:= ParametricPlot3D[ {Sin[t], Cos[t], t/3, RGBColor[t/15,0,0]}, {t,0,15}] Out[10]= -Graphics3D- I hope this helps. --Ian ----------------------------------------------------------- Ian Collier Technical Sales Support Wolfram Research, Inc. ----------------------------------------------------------- tel:(217) 398-0700 fax:(217) 398-0747 ianc at wri.com Wolfram Research Home Page: http://www.wri.com/ -----------------------------------------------------------
