I made Easter Earrings modeled after PEEP bunnies for my wife.  Color change with different filaments or print one color and use cheap nail polish to color the bunnies. Each bunny is a .4 height difference, so at .2 you will have 2 layers of color for each bunny. Use the slicer post-processing to pause at layer height and use the pause on the layer before the new bunny color. In my case for .2 layer height, it was paused at 9(10/11 color), 11 (12/13 color), and 13 (14/15 color). 

Printed with .6 nozzle for speed, but a .4 would reveal the eye detail better. I will end up using a toothpick to dot the eyes onto the finished print.
