ColorHueState (CHS) is an on-chain image machine rendering the heartbeat of the Ethereum blockchain. Each hash of the current block height is materialized into a chromatic composition of four concentric rings encompassing the RGB color space. CHS is connected to the incessant cadences in decentralized technologies – a continuous present of irrevocable time pockets with the opportunity for anyone to catch the visual glimpse of such unique moments. ColorHueState is a memento token of a quarter of a minute of permanence.

Drawing from the average Ethereum block time of 15 seconds a new CHS composition is generated four times per minute circa. Each block hash is unique and can be captured as an NFT (ERC-721) only once, by a single entity. Minting incurs no cost except network fees. Heads up minters, permanence is ephemeral!

The four rings of a CHS are composed of outer ring A, followed by ring B, then ring C, ending with inner ring D. Each ring starts and ends with a six-character Hex color code eventually making up the first 48 characters of a block hash. The hexadecimal RGB color space encompasses a total of 16,777,216 distinct alphanumeric color values of which 46,656 are permutations of only letters and 1,000,000 of only numbers.
