. Mixing multiple voices in the same paragraphs is plain painful to parse, and not something different coloring is going to resolve since it affects entire structure of your story.
Fantastic advice here. Really read this and get the basics of dialogue down. It makes a big difference.
I can give an example here of what he means. I'll give the same dialogue sections twice.
1 (incorrect): Tom was walking down the street when suddenly a police officer pulled up next to him. The police officer jumped out his patrol car and drew his firearm at Tom. The police officer yelled, "Get on the ground, don't move!" Tom was dumbstruck at this. Tom replied to the police officer, "But I haven't done anything wrong." The police officer ignored Tom and screamed with increasing volume, "I don't care, get on the ground now or I will shoot you." After the police officer had bellowed his last order, Tom's mother, Sarah, called out to the police officer from a nearby window, "Don't you dare shoot my baby, he didn't do nothin wrong." The police officer glanced up at Sarah, but quickly brought his eyes back to Tom. Tom still hadn't put his hands in the air. "You're gunna have to shoot me, cause I don't listen to pigs," Tom said, making a shrugging motion.
-This is incorrect and can be confusing. There are three characters here in one paragraph. It is confusing to switch between them.

-I'm sure this isn't perfect, but I hope you can see the difference here. Each time you switch characters in dialogue they get a new paragraph. This helps separate the different characters in a reader's mind and makes the dialogue flow far better.
