I am working on a 144-page booklet. I need to make an universal color change throughout the document wherever the original color appears (text, strokes, etc). I used to be able to trash the color in the color palette and I would be asked for a substitute. This doesn't happen anymore. Any other method?
You can Find/Change by Object attributes (see the red circles below). Do it once for
Fills (which will cover both text fills and object fills) and another time for
Strokes. A more detailed article on how this works here.
