So Flinters told me I ought to try out Pilot mechanical pencil leads instead of the Pentel ones I'd been using. Pilot doesn't make leads in the size of the pencil I prefer to sketch with, so I ordered a set of 0.7 mechanical pencils in all the lead colors they make, so I could test them out.

Holy crap! These things are amazing! And they're ERASABLE. ZOMG ...I'm going to have to order replacement leads, I think. I have a feeling I'm going to go through them pretty quickly, and each pencil only has two leads in it. This is a test piece I doodled up to see what the different colors looked like.

This means from now on I can offer refined sketches in limited color. =3 I'm totally okay with this!
