Texture paint problem

I have this scene setup as in the attachment but I cant seem to paint the color map in the texture paint mode. Also the object displays white instead of pure black as the map applied was generated in Blender and saved out as a PNG.

Any help appreciated.

Solved. Newbie mistake, the image wasnt selected in the UV/Image Editor.
