I think what you want to do is pick 4 random colors for the corners and then
color the midpoints of the rectangle with a color that is the average of the
colors at its endpoints +/- a random factor that has a magnitude proportional
to the length of the rectangle's side.  so if you started with the colors
(R,G,B)--------(r,g,b) you would insert a color 
           ^here
and its value would be ((R+r)/2+z*d,(G+g)/2+z*d,(B+b)/2+z*d)
where d is the distance from the first to second pixel and z is a random #
in the range -v<z<v.  By drawing pictures with different values of v you can
get smooth (v~0) or rough (v~2) pictures.  
Let me know how this works out, I don't have the resources to program for
255 color graphics (or even 3 colors)
