关于一群独眼外星人的眼睛颜色的问题

大神们，求助。。是这样的有这样一道题以下：

一共有100个独眼外星人，他们的眼睛颜色要么是棕色的要么是蓝色，已知有三个主人公是蓝眼睛的，他们有一个习俗，哪个人知道了自己眼睛的颜色就必须在晨会（必须参加）上***，他们没有镜子或者任何能反射光线看到自己眼睛颜色的物品，因为他们都不想死所以互相不谈眼睛的事也没有任何关于眼睛颜色的研究，有一天，一个外来旅行者参加了他们的晨会，对所有人说：“我发现我们没什么太大的不同，比如我看到你们只有两种颜色的眼睛，就像我在我的家里一样。问接下来的一个星期会发生什么事，解释假设和理由。

原题是英文的我可能翻译有误，以下是原文

skye, robin and royal are three members of a 100- member, one-eyed alien culture. these aliens are very intelligent, but their culture has a curious tradition. if they are ever able to determine the color of their own eye, which they know is either brown or blue, they must commit *** in front of the whole group at their daily meeting, at which attendance is mandatory.

the aliens have had no contact with the outside world and they have no mirrors or reflecting surfaces (for obvious reasons). further they never discuss eye color in any way because they all know what great logical brains they have and so are very hesitant to give away any clues about eye color. skye, robin and royal are the only blue-eyed aliens.

one day, a well-meaning space traveler visits the aliens, and at their morning meeting gets up and makes an effort at good relations by saying “your people and mine are not so different. for example, i see that you have two different eye colors, just like i do in my own family.”

what happened in the week following the visitor’s speech? carefully explain your reasoning and assumptions. if the visitor’s speech makes a difference, you must explain why.

如果他们相信地球人的话，所有人都会死。

因为事实上他们有3个蓝，97褐，所以每个人唯一的疑问就是自己是否可能是其他颜色的眼睛，比如黄色，地球人的话打消了这个猜测，所以他们都知道一共只有2色。

当然，如果他们中只有1个蓝眼睛的话。因为这个蓝眼睛会以为自己可能是黄色眼睛或者紫色或者蓝色或者绿色，但是你告诉他一共2色，一个蓝色一个褐色，那么他看别人都是褐色，就知道自己要死了。也就是你的信...
