Green/Yellow(?) Challenge - Shapes

If the picture on your first hint works out to:

then I maybe on the right track. 


Edited to add:
However, with the method I was trying, it will be too ambiguous - so I must not quite be on it.

Nice! I love puzzles! Not sure I solved this in the most efficient manner, but I got there eventually.

Assuming people have already looked at the first hint:


More directly:



Some additional things (that can be derived from the hint):



And finally, a question I have:

You know, I don't think there is. I had a friend try it out and he solved it pretty quickly using the hint(which made me think it was easy, now I assume he got lucky). I just now thought of a way to improve it, but I'd have to change the shapes into other shapes. Haha. Anyway, thanks for trying it out and sharing your thoughts

Edit: I realized the puzzle was a bit too difficult as it is, so I added a hint that makes it require less random guessing.
