Vertex Paint Modifier
Problem: Color map or ID map is a critical map in PBR. For this, we need to spend some time to color the vertex. For this switching between edit mode and vertex paint mode takes a lot of time. Also when trying to extend a particular color it's hard to match the same color if not saved.
Solution: So the idea is to create a "Vertex Paint Modifier" that paints the vertex based on angle, vertex group etc. Colors can be selected automatically or from a user-provided list of colors. This will save a lot of time on each model.
Benifits: With this modifier, I just need to update the vertex group information and the color attribute will auto-update. No need to switch to vertex paint mode and no headache to select a different color or match a previously used color each time.

I upvote even if it's possible to do it GN style. I would prefer to have a GN modifier/tool with this functionality included.
Imo, having some high level GN groups/mods/tools for common stuff already included would help a lot in work and learning. Starting with a proper example makes further customization more approachable.
Solution already exist as Geometry Nodes. And it's better because, You can generate whatever you want based on Your needs and not only that what modifier creator would have implemented.
How can I use GN to assign different colours to different vertex groups?
