The "Marshal Dillon" show is in black and white. The first time you see this show, you will note that Matt Dillon's hair is jet black, even his eyebrows. James Arness, who plays Dillon, had light hair in real life. As the "Marshal Dillon" series progresses, Dillon's hair gets less black. By the time "Gunsmoke" rolls around, Dillon's hair is a brown color.
