I had luck changing the colors with a header like this, where the last
two lines are the additional bits:

   #+PLOT: ind:1 deps:(7 8 9 10) type:2d with:histogram
   #+PLOT: set:"ylabel '%'" set:"style fill solid 0.5" set:"style fill solid 0.5"
   #+PLOT: set:"lt 1 lc rgb 'blue'" set:"lt 2 lc rgb 'red'"
   #+PLOT: set:"lt 3 lc rgb 'black'" set:"lt 4 lc rgb 'green'"

I know very little about gnuplot and even less about org-plot, though,
so there might be a better way to do this.
