Collider Slime

So this kinda worksI can mostly get it to conform to my shapes, where I have issues are. white seems to be dark brown, almost black, green seems to be greenish brown. if I want  to get any color close to what I need I have to up the abbe on the surface to about 50 or so. If I need it to be tranlucent, it's not an option that I can figure out. It would be far better to allow control of through the shader This seems to be almost if not completely excluded. anything I add looks a took a soft wax sculpted onto most of the object. Some parts stick up ssome parts were buried so deep in the object that the collision match causes it to crumple up unnaturally. Any thoughts>
