[Scribus] Pick a text colour...

[Frank Cox]

Gimp allows you to select your current draw colour by clicking on an
existing colour in the image.

As I was trying to match some new text to the text that was already
included in a graphic I had imported into Scribus tonight, it occurred
to me that it would be very handy to be able to set your current font
colour by clicking on an existing colour in your document.
