Scribus is very easy, specially if you make a Master Page (that are page templates). Then you can re-use the one you did as a template for your next tutorials. Finally you export as PDF.
You can configure a text box with the font, color and everything, and just copy and paste it for each paragraph.
Scribus is so intuitive that you can just use it directly without watching tutorials or reading anything, at least for me. Everything is in the correct menu, and everything is simple.
Trick: If you want a colored background you can edit your Master Page, make a box as big as your page and fill it with color, then lock it. You can add the page numbers and any header or footer to that Master Page, and just make pages based on that one.
