Transparent Diffuse Shader + vertex color modulation?

I’m hunting for the resources I’d need to either modify a transparent/diffuse shader to take vertex color into account and modulate that against the UV texture’s color channel I’m currently using. Is there a simple way to do this? Has someone already posted a modified shader that did this? Am I going to have to modify the shader myself, and if so, what steps would I need to take to first get the shader code for the transparent/diffuse shader used in unity?

Turns out the particle additive shader had what I needed. Thanks guys.
