That is a bit weird…

I think I copied your Shader and get this:

Also works when giving the Emission Shader a color.

It could be that the hologram is affecting the cones material….and if you increase the strength of the Emission in the cones, to make it brighter, more white, then it will indeed look denser, because the Emission Shader in Cycles actually emits light…

Still, can’t get the effect you are having. It’s not important, because you probably wouldn’t have been able to render everything with Cycles anyway, but if you want to post a link to your .blend file (via Dropbox or so), I will have a look at what is happening. (I’m curious…)
