例如，框架上的红色标记表示不允许进行闲聊。黄色标记可能表明闲聊是被允许的，但应谨慎对待（例如，避免询问对方的出生地或使用该地区以外的语言）。绿色标记则表示大多数话题的闲聊通常是受欢迎的。你甚至可以根据自己的心情改变框架上的标记颜色。你觉得这是个好主意吗？

For example, a red marker on the frames would indicate that no small talk is allowed.A yellow marker might suggest that small talk is tolerated but should be approached with caution (e.g., avoid asking where the person was originally born or using a language other than the main language of the area).A green marker would indicate that small talk is generally welcome on most topics.You could even change the marker color on your frames to match your mood.Do you think this would be a good idea?

问HN：为什么不使用颜色编码的眼镜来表示愿意进行闲聊呢？
