cel shading methods?

Hi
I was wondering what the best way to approach cel shading in Toon Boom Animate 3 is?

At the moment I am using the Colour art mode to hold all my colours and drawing stokes where my shadows and highlights are then flood filling the areas however I’m finding it can become a bit messy having everything all in the one place especially if I decide I want to change something later on.
So what are some alternative approaches?

You want to be using effects to handle the shading separate from the animation. Take a look at Tone

and Highlight
