Color as Identify - The unique 4-colors-ID string generator in JavaScript

The performance of ColorID is better than UUID and NanoID (The algorithm of ColorID is actually very similar to the UUID.V4)

If we use ColorID to represent identities in social networks, we can easily generate personalized social information for users, such as avatars, NFTs, etc.

The ColorID is consisted by 4 colors in the RGB channel from 12 unsigned 8 bits numbers (u8), so the theoretical total of ColorID is (2^8)^12 = 2^96 ≈ 7*10^28, which means that even if the ColorID is generated for every 7.8 billion people in the world every second, it will take 300 billion years to use up all ColorIDs. And ColorID provides safety by using hardware random generator, can also be used in clusters.

Because the Four color theorem, if we need to color the regions of any avatars or NFTs so that no two adjacent regions have the same color, four colors are enough!

Install

$ npm i colorid.js

Usage

import colorid from "colorid.js";

colorid(); // #5B34F9-#34F9DF-#F9DF4E-#DF4EB5
