You can use a ColorFunction as a fourth function in
ParametricPlot3D. 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.
