Rainbow Writings

Exploration Stage: Caramel Boulevard
From: Terry Tofficus
Description: The perfect choice for the Book of Good Deeds is rainbow ink, made from the first snow collected in a blizzard under the northern lights. Not only is it pleasing to the eye, but it is also useful. Could you take it off the shelf, please?
Completed: Thank you for your help! Text written in rainbow ink can change color. If the matter is urgent, the text turns red; if not, it turns green; if something can wait, but only for a while, it turns yellow. How sweet!
