I choose to paint the juggernaut in a neutral grey color, since you always see them painted red. Using blue for a highlight color to draw attention to the fa of the juggernaut and red on the sheild of the rider helps to draw your eye to focal points. On the rear left leg i painted the area around the khorne symbol as if the model was about to change to the traditional khorne red. Also the rider is pinned to allow him to come off when transporting him to games. I painted this model a while ago and felt it was time to go since i have only ever used it once and needed to make room for some new models.
