Raron,
I suggest the Edwards AFB Chase Aircraft scheme, basically white overall with large areas of International Orange applied to the vertical fin and wings-quite vivid in most background conditions. White wingtip missiles also help and I've painted the nose cones flat black with dayglo red/orange applied to the rear and fin areas of the missile. You can use rattle can or Testors Model Master enamels to color the missile. Good luck with this.
Rgds,
