The following code completely reproduces the bug, and the #sys shows how it deslocates. Taking of some f the lattices also doesn't fix, it can be checked.
Now I understand what you meant: in the figure you linked to previously, the color of the single “stray” site does not match the color of the “humps” with which it shares the same site family. Before you sent the example I wrongly believed that your issue might be about the sorting order of sites with regards to which there used to be some problems. However, I would be surprised if the color issue you observe was caused by matplotlib. It should be able to plot a circle in the color it is told to do. So that’s indeed a strange problem! However, I cannot reproduce it. In your script, I uncommented the line marked with “bug?” and obtain the attached plot. The separate site has the same color (here: yellow) as the two humps that are made with lat_sc, as it should be. This is with Python 3.9, Kwant 1.4.3, and matplotlib 3.3.4, running on Debian stable. What is your environment? Christoph
