Both are necessary. The blended version is the weathered granite look,
the crisp version is the fresh granite look.

No secret there: just for convenience while testing the omega, lambda
and octaves. The top row of the experiment shows start and end
variations both. I guess that more differences would be shown with a
"simpler" colour_map? Not sure about this. I want to investigate a bit
further.

I guess this is almost as close as you can get to a believable granite.

Maybe. I am not sure yet about what he means.
