This logo shows Gestalt's principle of closure - despite the colors, we see the little vertical cut out in the center. With that line we assume the figure is a peacock, and closure fills in that image, our perception completes the whole. Also shown here are principles of Proximity (by the closeness of the separate 6 colored pieces), and Similarity because all the colored pieces, and the cut out piece in the middle, are the same shape (other than the cut out we assume is the peacock's beak).
This logo concept is quite different from other 3D designs of the same letter. If it was to be shown from the front, you would only be able to see the line in the middle, where as if moved a little to te side, the flat sides show up. Nice optical illusion.
