Colors of Seville Collection. 6 photographs taken on the streets of Seville, Spain. 4 separated editions, limited to 6666 1/1 NFTs, minted using an ERC721 smart contract on the Ethereum blockchain. Collection migrated from Polygon POS (Chain ID 137), first to Polygon ZkEVM (Chain ID 1101) in March 2024 and then to Ethereum (Chain ID 1) in February 2025. In September 2025, the collection has been migrated to the second version of NFTs on Ethereum. Same photos, but improved NFTs with the correction of minting errors. Regarding the structure of the metadata: The Token ID of each NFT contains information about the edition and the photograph that certifies this NFT. Example: Token ID 2260 informs us that this is copy 2 of the Ruta al Palacio (Gold Edition). Some NFTs TokenID ends on 1 or maybe 2. This means that the NFT has been reminted due to an error in the first mint. The erroneous NFT and the previous version has been sent to the burn address.
