Hi inspection-duty,
There are two presets in the Asset Browser. Are they working for you?

"Emitter based On Texture" and "Emitter based on Vertex Color" (Both use Vertex Color for the field in the Surface Emitter. That might be a limitation if the mesh is not producing enough Vertex points.
I have tested both with the current version, just in case.
Let me know if you have a question. I'm happy to look into it.
Enjoy your weekend
