Lightroom Book module, background colour on text boxes
Hi,
Apologies if this has been asked before - I haven't been able to find anything.
I'm working on a Blurb book in the Lightroom book module. Is it at all possible to add a background colour to text boxes? For example, in the attached image, is there a way to make the caption white text on a black background? If so, is it possible to adjust the opacity of that black background?

I love the idea of being able to work on everything within Lightroom, but the book module is seeming a little limited...
I've always used Blurb BookSmart before, but it's not supported in Mac High Sierra so I've been forced to change. BookWright seems limited too, and I don't have a subscription for InDesign (plus building a book from scratch is a bit beyond me).
If anyone could shed some light, or offer tips on a workaround, it would be greatly appreciated. (I have considered doing variations of the background image with coloured boxes strategically placed, but I'm hoping that won't be necessary...)
Thanks!
