I want to add color to my line art layer when coloring artwork that was scanned in. In Photoshop this could be accomplished by pasting the lineart into a mask and inverting it, then adjusting the levels of the mask to let the colors layers beneath the lineart layer shine through thereby coloring all the lineart in one shot as opposed to going over each line with a color brush. Is there a way to do this in affinity photo?
