How to acheive a holographic/spectral look in c4d?

You could try a rainbow map in the specular

Like other anon said, rainbow coloured clouds in PS, apply as reflection map/ cubemap.
The geometry will make a big difference in this method, tho

Alternatively if you're aiming for something interactive, just set the object to reflect the sky... Crash 3 used it for water and it looks pretty close to holo stuff, only it's solid blue.

Map a rainbow ramp in the specular/reflection to a perpendicular falloff. In Maya with Vray you just need a sampler info node. I guess there's something similar in C4D.

In C4D R18 is a new shader called "thin film" shader. I think its made for stuff like this.
