Shuriken Texture Color Problem

Hey all. I didn't know where to stick a Shuriken question, so I figured here was a good start.

When adding a material (texture) to a particle, the applies the default color of white to it. This overrides the textures actual color. For example, black smoke becomes white smoke. Changing the start color to black effectively makes it transparent. There must be an option to turn off the coloring in the Shuriken inspector, but I don't see it. All the textures are modified by the Start Color property.

Anyone know if I'm doing something wrong or is this Shuriken working as intended?
