포토샵 칠 레이어 일괄 변경?

You can automatically change content, including the fill color of multiple layers, by using cloned smart objects. Convert a layer to a smart object, then duplicate it with Ctrl + J. This will create cloned smart object(s). Changing the content of any cloned instance will automatically update all other clones.

I don't know of any way to change the color of multiple fill layers at once. It is possible it couild be scripted.

You can link layers together so that they move together, but that doesn't change their fill color.
