G'day from Australia.

I hope some kind soul out there can help me.

I have two layers.

The top layer is a transparent layer and consists of some graphics in black.
The bottom layer has various random colours and fills the screen.

What I want to do is selective colour the top layer by pulling up the colours from the bottom layer onto the black images. Then I want to delete the lower layer leaving me with the top layer black sections now coloured with the colours from the bottom layer.

How can I do this?

Thank you and please keep the answer simple, I have just started using Artrage.
