I have painted my object with vertex-color on vertex-paint. How can I make the color visible in object-mode or edit-mode.
Meaning, how do I implement the vertex-color onto my faces so that I can see them on object-mode or edit-mode?
In 3D View, hit N to bring up the right panel, then enale Textured Solid.
Now in Object Mode and Edit Mode, you will see the vertex colors.
EDIT: This appears to only work with Blender Render.
The vertex color is show in 3D View depending of your Viewport Shading
One menu next to where you choose Edit Mode, Object Mode, Vertex Paint, etc., the icons look like spheres showing different textures. You can switch between them. To see your vertex paint, Texture is needed.
If you need vertex paint on your renders, it's another story
(Vertex Color Paint in Properties Editor > Materials > Options).
