I'm very new to blender, I have imported a mesh into blender with vertex colors and I can see the colors appear in the blender screen and the camera view, however when i save the image it appears to have lost all color information.

The code I'm using to capture images is

 bpy.context.scene.render.filepath = "/home/josyula/Programs/blender/img.jpg"
 bpy.context.scene.render.image_settings.file_format='JPEG'
 bpy.ops.render.render(use_viewport = True, write_still=True)

enter image description here

I have attached the images of rendering screen and the saved image enter image description here

It is because your object has simply no material at all.

so press new, change the color and voila - you have a color.

The color you see in the viewport is just a vertex color, which won't be rendered if it isn't used by nodes in the material.

I had to add vertex colors from the material properties as Chris pointed out.

The answer that really helped me is How can vertex paint be rendered?
