What is it?

This coloring is designed to "frame" (draw the contour) of the tiles composing Penrose tilings. It is designed to be used with "Pixel" in mt.ufm.

Parameters

Shape

You have to make this parameter match the "Mode" parameter of the Penrose Tiling transformation. For a standard framing, use the "Frame" option in the coloring and in the mapping.

Thickness

To modify the look of the frame.
