Reply To: How to change text colour in one of several threaded text boxes?

Well if your text is all threaded and it’s a paragraph and you apply a different paragraph style – the entire paragraph will change.

An Object Style only allows Paragraph Styles, not Character Styles, therefore your threaded text frames are applied a Paragraph Style which turns all paragraphs it’s attached to “white text”.

There is a clever way to do this – although I don’t recall all the steps – I’ll see if I can dig it out of some internet searches.
