I had an enquiry about how to use the Listbox.CellTextPaint-Event for coloured text.
While answering I realised my own routines were usually rather crude, so I decided to write a kind of formattedText listbox subclass for listbox cell text properties like color, weight or size. In case someone may find it useful: Here is the German blog post (online “translation” available with built-in Google translator) together with the link at the bottom of the text. The project is documented in German and English: https://xojoblog.me/2018/01/29/bunter-listboxen/
