Hexover uses the colors from Colorly and the search library kd-tree-javascript to provide an API for matching a hex colour code to similar commercially available swatches, such as Pantone colours.
To run Hexover as-is:
npm install
node index.js
Hexover will run on port 3003 by default, but you can specify one when you run it.
For example:
PORT=3210 index.js
Hexover will output the 3 nearest colour values in its index to the hex code argument. If you want to change the default, it is the second parameter to tree.nearest in index.js and you can change it there. If Hexover finds fewer near matches than this value requests then it may return a shortened or empty result.
By default Hexover only searches against the Pantone colours from /src/pantone_data. There's a lot more data from other colour books in Colorly's dataset. That's all in /src/data, and you can index it by manipulating and running ./build_index.js.
