Minecraft wiki entry for Easter_eggs, associated text: Naming a sheep "jeb_" using a name tag or a renamed spawn egg causes it to continually cycle through all colors a sheep can be dyed. When sheared using shears, however, the sheep drop wool of the original color of the sheep rather than the color that currently appears on the sheep. In Bedrock Edition, if a sheep is named jeb_, and then sheared, the leftover wool on its skin continues to cycle through all the colors.
