Protagonist
My first character is John. His basic color is red, as shown below. This color represents his love of family, those related by blood. He has a monochromatic scheme, which will help with the contrast with his antagonist.
The way John is lit is by a softer light. This light is stronger than the ambient light, but not by much. This shows that John is a regular guy who wants to do good, but he is not going to show it off. He wants to do what is right and move on. He is more in the background, but those paying attention will notice his actions, but he will not flaunt them to impress others.
The basic shape for John is circular. This will contrast with his antagonist, and show that he is more flexible, and tolerant. He respects those with other beliefs, but will not tolerate wronging others. To keep with the theme, John is a bit big in the waist. His head is a bit round, and he has a bit of a slouch. He looks like a normal guy.
Antagonist
Mordecai is the antagonist. His color is a monochromatic green, which is opposite of John's red. This color represents his greed, due to being from a poorer family and becoming successful by his own hand. This color also represents jealousy, mostly from being alone most of his childhood and seeing others having a good time with each other and being excluded from the festivities.
The lighting that would be used for Mordecai is a harsh, fluorescent light with deep shadows somewhere on him. his shows his dark deeds, and desire to let everyone see him and what he is doing. For most of his childhood, he was basically forgotten or ignored, so now he wants to show everyone what he is actually capable of. But he is very businesslike in his actions, hence the fluorescent, somewhat blue lighting.
Finally, his shape is very square. Taking a business like approach, his outfit, a suit, naturally is square. But to fit better, his facial structure is very angular. Due to coming from a messy past, he wants to prove that he can become better. To him, this means cleaning himself up and making things perfect and orderly. Thus, corners and straight lines are preferred over curved, natural lines.
