You need to add the coloring function as a fourth component, as in the
following example:
ParametricPlot3D[{Cos[t],Sin[t],t/10,Hue[t/(8Pi)]},
{t,-4Pi,4Pi},PlotPoints->200]
To get a solid red helix, substitute RGBColor[1,0,0] for Hue[t/(8Pi)].
Coloring curves with ParametricPlot3D allows you to vary the color, but
using the PlotStyle option with 2-dimensional graphics functions, you
can only use solid colors.
