Hi Josh,
There is a typo with the vertex color type. It looks like you want to use
8bit values, so If you change *c4b* to *c4B* it should work.
By the way, is there a specific reason you're using Domains directly,
instead of just creating a Batch? There is nothing wrong with your
approach, but using a Batch might save a bit of boilerplate.
