stone walls and floors I want to create very detailed backgrounds.

So how would I create my own backgrounds good as this?

Didn't work.

I really don't get it.
I put two shapes one normal blending and other the multiple blending. didn't work.
I'm not talking about the bg in video I'm talking about the voodoo dolls when they change color in animation.
what does black got to do with changing color?

how would I make backgrounds like this?

I don't get it, how would I do that?
Please Show me how to do it.

In princess and the frog - friends on the other side - voodoo dolls drummers change color how would I do this in anime studio pro 11?
