A Tone layer is a special layer in Manga Studio that simulates those plastic shading and transfer sheets used by traditional graphic artists. But in Manga Studio, Tones can be dynamically changed at anytime for different haltone patterns, colors, gradient values, or completely different textures. Even better still, I can brush on Tones or erase them where I don’t want them. Yay! No more mutilating my fingers with an x-acto knife! Using multiple Tone layers, Tones can be applied additively just like the real thing. Or, if that’s not what you want, you can insert Mask layers between Tone layers to give the Tone above the mask a specified ‘opaqueness’. I use tones in Brudders mainly to give these simple drawings just a little bit of depth and roundness.
