# Prime Machin The Prime Machin collection explores the dynamicity of rarity by allowing users to decide whether to upgrade their NFT to include color, or keep it black and white. Once colored, it cannot be uncolored. This allows the community to determine what configuration is most valuable. Is it the first Machin to be upgraded to color, or is it the last Machin to remain uncolored? ## Collection Migration The Prime Machin collection originally released on the Craft NFT marketplace on Icon, however, it is poised to migrate to the Clutchy NFT marketplace on SUI in the near future. ## Lore Read the lore on the smartest group of Machin on the main Machin page [here](/nozomi/collections/machin.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
