Color Hashing in Elixir Using Erlang's phash2 Function

Source: andrewian.dev

Andrew dives into a favorite hashing function from Erlang, the phash2, which lacks a direct Elixir equivalent. This function uniquely hashes Erlang terms to integers, regardless of the machine architecture and ERTS version. Its abilities include hashing any terms, not just strings, and constraining hash output to a specified range. Andrew illustrates how phash2 can be employed to generate color hashes that could be used for stylizing user interfaces, such as giving chat bubbles unique colors based on user names. By tweaking the output ranges, more appealing color hues can be achieved. Andrew's explanation is practical and geared towards Elixir developers interested in leveraging Erlang functions to enhance app features.
