Something that I’ve been doing for awhile now is pencilling my comics with colored pencils (I was inspired after seeing some sketches by Marian Churchland on Instagram). What I like about doing this is that they let me build a drawing without having to erase too much. I can start with an orange, and then when I want to nail down a line, I can switch to a purple or blue.
I do this on the finished page, also. I find it really helps with distinguishing, back-, middle-, and foreground.
I also find that the colors are so light that they drop out when I play with the levels after I scan a page. That means less erasing and less of a chance of the pencils muddying the clarity of the inks, which can happen with graphite.
Colored pencils can have their drawbacks. It’s hard to keep them as fine as graphite. And sometimes they are so light that I have trouble seeing them. Also, if I go too crazy, there can be a waxy build-up on the page which can impede ink flow. Though the easy fix for that is to finish my pencils fully on another piece of paper and start a new one for final inks.
Still, for me the benefits outweigh the potential negatives. And sometimes the pencils just come out looking really cool.
