Hi, I'm new here, so I hope you can forgive me for posting a question that may have been answered before.

I'm currently finishing a two-page article on Calibre for the leading Swiss magazine on print and digital publishing (publisher.ch).

Personally, I've used Calibre only for my own purposes and thought (and still think) this is an amazing piece of work. However, as someone who doesn't consume comics, I wasn't aware of Calibre's capability to open and convert comic books file formats. Since I wrote an article on Krita (https://publisher.ch/2018/02/05/mehr...malwerkzeug-2/) for the magazine, I thought that would be an interesting aspect for the readers.

So I downloaded a CBR file and converted it to EPUB only to discover that all colour images in the ZIP container had been converted to greyscale.

Hence my question: Is this a bug or a feature?
