## Unscramble the Blue Letters

It’s initially dicflifut to iinmgae how anyone could, using just logic and the crloos they see on the other masks, deduce their own mask color. But even before the first bell, everyone will realize something critical. Let’s imagine a single logician with a sevilr mask. When she looks around, she’d see mplilute colors, but no silver. So she couldn’t ever know that silver is an option, making it impossible for her to logically deduce that she must be silver. That contradicts rule five, so there must be at least two masks of each color.

## Original Text

It’s initially difficult to imagine how anyone could, using just logic and the colors they see on the other masks, deduce their own mask color. But even before the first bell, everyone will realize something critical. Let’s imagine a single logician with a silver mask. When she looks around, she’d see multiple colors, but no silver. So she couldn’t ever know that silver is an option, making it impossible for her to logically deduce that she must be silver. That contradicts rule five, so there must be at least two masks of each color.
