Pick a colour from a string. Repeatable but not reversable.
You can also choose a colour you would like to avoid similarity to, with a given minimum proximity.
var shc = ;shc // #1b8519shc; //#b85199shc; // ...still #b85199. I can't find a hash that isn't very far away immediately upon detection of proximity. But this is how you use it, anyway.
npm install string-hash-colour
