This is how to make chromatic art.

Go to the animation tab.
Make something (I suggest using color red to make the chromatic vibe)
Then use the shape selection tool. Put it on the main color of your thing.
Move the shape once to the left or right.
(It doesn’t save since it’s the shape selector)
Here you have it!

(Don’t mind what I made I was messing with the big boy boss animation in my testing / development area for barricade)
