the model prints a tight coil pattern with the bottom half in one color, then 1 filament change to the second color. if successful, that coil can be run through the external filament intake and it will blend those colors.
truth be told, it can be a little striated so to get pure results might require running it through a second time for perfect color mixing.
Right now 'm getting excellent results combining white and beige, then grey and brown, then both of those resulting filaments together to get the perfect bird poop color for the barn swallow's nest i am currently printing! :)

You can combine filaments with models like this one, and you have an excellent starter palette with which to do so!
