Is there a way to recolor lines without having to redo them? In like the same way of Photoshop where you’d add a cllipping mask and can isolate the line art so you color just the lines alone.
You can just keep the line art on a separate layer. You can use replace color to change any colors after that. There’s also the shading ink with the pen.
You can also use Lock Alpha on the same layer to colour just the lines. The option is under the Ink button (next to pixel size)
