Ok! So this is what I mean— hopeully this explains it!!! Pretty much what you want to do is draw your lineart as normal (I use a pastelly/greyish bg using my usual lineart colour + linear burn just so I’m seeing what I’m ending up with/it’s less harsh than inking in black) and setting up your FLATS is the important bit. You want your lines to be on linear burn so you can see what stuff looks like— unlike normal basing, you want the colours to go all the way under the line. With blacks or lines that you colour yourself, you can use the opaqueness of the lines to hide your messy basing. With this method you want to be pretty precise, or you will miss little bits, and it will look messy. Unless you are me and that is what you’re going for, lol.
If you’re someone who likes control over their images, this is not the technique for you, this is like JESUS TAKE THE WHEEL lineart mode. I like having the control with opaque lineart I colour myself but it takes a thousand years, so this is the method i refer to. I have linear burn on 100% right now, but past pages were 85% or lower. Just depends on how strong you want it to look. You can do a lot with this TBH! and it’s a fun way to do coloured sketches that look good quickly— I drew this in like 5 mins.
