This part is confusing. I am familiar with color keying overlays: you
say the color to use is "magenta" or #FF00FF.

First you say that you use a magenta color key to "make transparent
some area of the upper layer."

BUT THEN

You say "When this happens I need to make that area transparent."

Isn't it already transparent from using the magenta color key?

You're being confusing!
