Shuriken color shader property

Questions & Answers
1

Actually quite a simple question.
Does anyone know what specific shader property that Shurikens “Start Color” and “Color Over Time” functions affect?

Is there a specific name for the property? or is it using something like the MainTexture colors?
(and how would I implement it in a custom shader)

I figured it out. Shuriken is changing Vertex colors. I did it like this:

Properties
{
	_TintColor ("Main Color", color) = (1,1,1,1)
}
CGPROGRAM
#pragma vertex vert
#pragma fragment frag

float4 _TintColor;

struct v2f 
{
	float4 color : COLOR;
}

half4 frag( v2f i ) : COLOR
{
	//Use i.color here
}

struct appdata_t 
{
	float4 color : COLOR;
}

v2f vert (appdata_t v)
{
	v2f o;
	o.color = v.color;
	return o;
}
