How would one change the color of the player object if the player chooses "Orc" in the start screen?

For instance, each character is edited based on what you actually choose ingame.
I.e. Elf is taller and thinner, dwarf is shorter and fatter, and human is unchanged from the base gameobject.
I, however, don’t know how to change the color of the gameobject from this choice menu for the orc character, which I’d like to make into a pasty green color.
Any suggestions?

//code here

#pragma strict

function Start ()

{
if (CharacterCreation.Main_Character_Human == true){
	// Nothing needs to be changed if main character is a human.
}
if (CharacterCreation.Main_Character_Orc == true)
{
	// Let's make the orc green and a little bigger than the human.
	transform.localScale *= 1.2;
	
}
if (CharacterCreation.Main_Character_Elf == true)
{
	// The elf can be taller and thinner than the human.
	transform.localScale += Vector3(0,10,0);
}
if (CharacterCreation.Main_Character_Dwarf == true)
{
	// The dwarf can be shorter and fatter than the human.
	transform.localScale *= 0.65;
	transform.localScale += Vector3(15,0,0);
}

}

function Update () {

}

//what would I have to add here, and where would it go?

The right answer will depend on context…how you modeled the characters, whether you are setting all the mesh to a specific color or only some areas, whether drawcall batching is an issue. Here is an answer outlining how to color objects:
