This dual coloured heart is designed by Andrey Lukyanov, an Ukrainian origamist, who has designed a whole bunch of heart/love-based origami! Using Google Translate, I gather from his website (which is in Russian), that this heart represents 2 halves of love which builds a new life.

As far as the model goes, the creator has made a detailed video on how to fold it (link below). After the initial pre-creasings, the model is collapsed on these creases. That point is not very clear in the tutorial. It took me a couple of tries to get this right. Another potential problem area is pleating the leaf. I had used 6-inch paper and the pleats are really tiny!

The obvious choice of paper is a single-sided red paper. I have used pearlized momigami paper and I love the texture it adds to the model.
