Varying colors of procedurals

Is it possible to change the colors of the procedurals which already contain shaders?

In Arnold for 3dsMax, it is possible to see the contents of Arnold procedural.

But I can't see any contents tab in Houdini version.

You could also use the set_parameter operator to change the shader in the procedural. Tutorial here.

Nevermind. I figured it out myself.

I just need to create a user data float attribute in the shader and it works with per-instance attributes.

OSL pick instance:

For max at least, we also have something like

getattribute("nodeName", Name);    
    Hash = hash(Name);


This returns the instance ID which can then be shuffled around or whatever.
Its a pritty generic procedure, so it might work for you as well.
