这里有一个实现方案，可以让你设置六边形单元格的颜色，并且还可以创建自定义边框颜色。
这是全手工制作的，只用了1小时参考你的网站。你可能需要根据自己的需求进行适应，但似乎可以正常工作。

我尽力对我的代码进行了适当的注释。如果您有任何不清楚的地方，请不要犹豫，请求解释。
祝你好运 Arthur Vaisse。
NB：脚本在Python 3上运行。绘图有些粗糙。可以像https://mail.python.org/pipermail/tkinter-discuss/2009-April/001904.html中建议的那样添加抗锯齿来改善Tk画布。
tk.destroy和tk.quit方法。但感谢你在这里指出这个错误。我会编辑代码的。 - Arthur Vaïssefrom hexalattice.hexalattice import *
