Tiago: I understand that in most cases the code is required. However in this case I am asking a different question. Since I can verify that, all the way through processing, my initial edge color property map is preserved, and I cannot delve into the libgraphtool library, I was hoping that someone could tell me if there is some phase of color manipulation in the final drawing library that I don't know about. In other words, where do all the unexpected, unwanted colors get introduced? Thanks and Merry Christmas JP ________________________________ From: graph-tool <graph-tool-bounces@skewed.de> on behalf of Tiago de Paula Peixoto <tiago@skewed.de> Sent: 24 December 2019 06:15 To: Main discussion list for the graph-tool project <graph-tool@skewed.de> Subject: Re: [graph-tool] Four-color problem :-) Am 22.12.19 um 22:30 schrieb JeanPierre Paillet:

Since you haven't provided a single line of code, it's rather difficult to guess. -- Tiago de Paula Peixoto <tiago@skewed.de>
