Okay, so I've seen the other answers to this here in Blender Exchange. However, as far as I can figure out those textures were not saved when created in texture paint mode.

I added an **external** texture to my object:

...then I switched to texture paint mode and the texture changes to a complete black texture:

However if I switch back the texture while in texture paint mode it still keeps my object black:

Is this a lighting problem? Or am I not importing the external image correctly? I have tried packing/saving the image after importing it and putting it on my UV Map and then switching to texture paint mode, but it still occurs.
