retrieve named colors

Hi-
I am trying to use the existing colors in my colormap to color specific
contours in my contour plot. How do I assign the value for col(q) in the
example below? Or should I be using the gsnSpreadColorStart (and End) to use
the different colors individually for each specific contour?

colors=(/"white","black","white","blue"/)
  gsn_merge_colormaps(wks,colors,"radar")

res@cnLineColor = col(q)
