When using a Dye item to color the text of a sign, the Dye 'passthrough' to the item behind it. It the item is a sign, it will also be dyed at the same time. Imagine the following setup (with player facing to the right, and the signs installed onto one another):
Player S1 S2 S3 Chest
If the player clicks S1 with a dye, both S1 and S2 will get colored;
If the player clicks S2 with a dye, both S2 and S3 will get colored;
If the player clicks S3 with a dye, S3 will be colored, and the Chest will open.
That's hilarious. I noticed that when dying/glowing a sign it will still open a chest behind the sign, but had not noticed that it also 'pass-through' dyes.
