Expressions: Color control: batch control
I have a silhouette of a pigeon flying on one layer. It uses the TINT effect to color it blue. I want to duplicate the layer many times, so a flock of blue pigeons fly by.
Anticipating the client might want to change the color, I’d like to use a control layer, probably a solid, with Expressions to control all the layers’ color simultaneously.
How would one do that?
(I could do a precomp mask, but now I’m just interested in controlling the TINT effect with an expression, which solution isn’t leaping out at me. Also, w/a precomp I’d have to jump back and forth, what a PITA.)
