Looking at your Pic`s it looks for me as you have no Image assigned to your unwrap…try to drop in a Image in your UV/Image editor window. Hope that was it.
Getting Started
Once you have un-wrapped your model to a UV Texture (as explained in previous pages), you have to:
Load an image into the UV/Image Editor (Image->Open->select file) , or
Create a new image (Image->New->specify size) and saved it to a file (Image->Save->specify file).
not certain i reloaded the file with a pic
and in the uv editor bottom header i was able to turn on the Paint function
and i can add some color in UV editor now
see pic
but i still need to do it inside the 3D viewport
in texture paint mode i can see the circle for the brush
but i does not color anything not cetain why ?
mind you my model have a very low faces count
so normally i guess this should be used on model with a lot more faces
and in the uv editor bottom header i was able to turn on the Paint function
well i would say now switch in your 3D view to the Texture Paint mode press F9, adjust your Brush in the Paint Tab (Opacity, size, whateveryoulike) and Paint onto your model.
Lets try folowing.
Open your model, unwrap it, drop an Image to your unwrap.(I guess you are allready at that point)
Switch to Texture Paint mode and drawtype Textured.
If your model is now white and you can paint over it but changes (brushstrokes) only apper in your UV/Image editor window then i would say your Picture is not an Square Power of 2.
From your tutorial link
Texture paint is very fast and responsive when working in the 3D window and when your image is sized as a square, power of two; 256x256, 512x512, 1024x1024, etc.
Try to change it in Gimp/PS what ever
If You can paint over your model in Textured mode but you cant see your texture in edit or object mode try
F7/object buttons —>Tab Draw —> Drawtype. Turn on shaded.
ok i remember this power of 2
but tough that this was a must for BGE
but may be it would help also for the Texture painting
but don’t remember seeing this in the wiki page !
i’ll test that too
now one thing i tested is that in the 3D window i don’t see the color added being in texture paint mode
but i can see in the UV editor the stroke of brush being added but not visible in the 3D viewport
so may be we are not supposed to see it in the 3D viewport ?

Thats what happens for me too if the Texture is not a square, power of two.
Maybe a Picture is clearer. Added a simple cube and a bit more complex mesh.
Sounds a like the Question you did here allready. Maybe you become answers fitting your liking more if you explain there what you are trying to archive with that hiding.
There are some methods to merge UV/Texture maps, 3 things i wanna mention will hopefully help you to start your research what fits best for you.
merging Images/Textures with alphachanel. You could lay them on top of each other and bake to a UV map. I think (without searching myself now) there are tuts out that explains it great.
stencil maps. They work like masks and you can blend Textures together with a black/white, greyscale map. To get all in one final map you can do a Texture Baking. http://www.yofrankie.org/glsl-splatting/
and at last i wanna mention Projection Painting. Here you Paint diffent Images/Textures direcly in an image. Thats close to what you have done allready here. http://www.cgcookie.com/articles/projection-painting
iv’been re reading all the wiki pages on UV and some tut tpp
and not easy to grasp all the definitions little tricks and to understand it
but i’m beginning to have a better understanding of it with time and lot of practice
and help from forum here
anyway i’ll re test and i think it should wiork this time at least i hope
for the painting projection i tried it check the video a few times but it’s a little difficults to understand but i 'll check the video again and may be it will go better this time
