How to edit elements simultaneously on all artboards in Photoshop?
I have several artboards in Photoshop on every artboard placed text, how change color of this text only in one place that the changes are applied to all texts on artboards?
Set your text. (or create whatever object it is you want to create)
Convert the text layer to a Smart Object.
Copy and place that smart object where you want it (on various artboards).
To change the color on one artboard, add a Color Overlay Layer Style to that smart object.
To change the text across all artboards, double click one of the smart objects and edit the original text layer.
