Wool

"Wool was added to Minecraft a looooOOOong time ago - in June 2009 during the game's "Classic" development phase. It was originally called cloth and came in sixteen different colours that aren't quite the same colours we have today. Knowing that wool was originally cloth helps to explain why you use it to make paintings - I don't know anyone who paints on wool in the real world. Leather armour was also originally made using cloth and called cloth armour."

- Duncan Geere

Wool is a block derived from sheep that can be dyed in any of the 16 different colors, which are white, orange, magenta, light blue, yellow, lime, pink, gray, light gray, cyan, purple, blue, brown, green, red, and black.

Obtaining
Wool can be broken using any tool, but shears are the fastest tool to use.

Sheep
1 to 3 wool is harvested by shears on an adult sheep. If unshorn, sheep will drop 1 wool upon death. The wool dropped will be the same color as the sheep's wool. The drop rates are not affected by the Fortune or Looting enchantments.

White, light gray, gray, black, brown, and pink wool can be found naturally on sheep. The rest of the colors require dyeing sheep.

Natural generation


All wool colors except for magenta, pink, and purple generate naturally as part of structures within woodland mansions.

White and yellow wool generate in shepherd houses, fletcher houses and meeting points in plains villages.

White wool generate as woolen tents in pillager outposts.
