Is it possible to apply vertex colors to vertices that aren't part of a face?
I've tried using vertex paint mode in the Blender application, and also directly modifying a vertex paint object via python, neither or which worked.

The wiki says:
The color of all visible planes and edges attached to the vertex are then modified with a gradient to the color of the other connected vertices. (Note that the color of non-visible faces are not modified).
As I understand this, it works on gradients which are not available without edges and faces. Thus you can't paint isolated vertices.

$\begingroup$ @ajwood I already wondered what you're actually trying to achieve, you also can't add custom-properties to vertices , check the last post by codemanx here: blenderartists.org/forum/archive/index.php/t-313260.html I wouldn't have expected such. An alternative that always works in scripts is a mapping: vertex-id to custom-data. $\endgroup$– stackerJun 12, 2014 at 21:35

$\begingroup$ I'm doing some scientific visualization.. I've got a few thousand edges/curves, each with a value which will determine their colour. I can either add them as separate objects (color based on a whole-object property) or as one big object (color based on _______) $\endgroup$– ajwoodJun 13, 2014 at 15:44
