Color individual faces after modifier It is possible to color individual faces of a model by going to edit mode and assigning different textures to each face.

I'm using a low poly model to which I apply a subdivision modifier and subsequently a decimate modifier. When I go to edit mode I only see the faces of the original mesh. This does not map well with the final result and therefore I'm not able to color it appropriately. How could I color individual faces without applying the modifiers.
Once you use a Generate Modifier (decimate counts as well) you don't have much control over the mesh anymore. Since modifiers are by nature dynamic, you can't change individual faces, since they might not exist in another frame.
Usually you would use vertex paint in a situation like this, but that's also not easy.
One method to cheat I can think of right now is: Use a texture, unwrap your model and make the decimate modifier respect the seams. It's fiddly, but you might get this working.
