Pink Wood was a classified and featured wood type in Lumber Tycoon 2 that has been removed from the game. In the game files, this type of wood is labelled as "GenericSpecial". Its exact or approximate release date is unknown and was never stated its return to the game again.
It was available on consoles until deactivated, and could be rarely found spawning inside Oak Wood trees. Once Defaultio found out, he quickly patched it and removed all instances of Pink Wood from blueprints, trees, and others.
One week after discovery on June 28th, 2016, the wood was confirmed to be an extremely rare wood type with a spawn rate of 1 to 1,000,000; and was available during a certain period. On July 1st, 2016, the wood was decommissioned from the game and all instances of Pink Wood were replaced with Oak Wood.
Sometime in February 2019, exploiters have managed to fill blueprints with Pink Wood, but it will convert back to Oak Wood once the user has reloaded their base or rejoined the game.
The code string that allows the wood to spawn still exists in the game code, however, is not functional as the code has been converted to a comment (a text string that does not affect game functionality), and the log and plank value of the wood has been changed to 0 making it useless to sell it.
