For the pigment I went to a local concrete supply company. They had many colors to chose from. It’s a powder and a little goes a long ways, Here’s the link to the manufacturer of the pigment.

yeah, mostly what
@moke said. I used the same material, but mixed in some of Quikretes concrete dyes at mixing stage. I bought, black, red, and brown.
I used expanded metal lathe to creat an initial form work, and did several stages of concrete. 1 stage to coat the lathe, 1 stage to get some more texture shape and dimension, and one more for final texturing and shape. To get the final texture, I used a combination of metal knives and tools then did a paint brush texture, and as it was drying, I would spray the entire piece with a spray bottle to expose and sandy bits in the mix and rough the whole thing up.
the idea was inspired by a slab Moke poured. Mine came out considerably different, but I wouldn’t have used this material otherwise!
