npm i
coffee index.coffee

Alternatively for MacOs / Homebrew:

brew install coffeescript
coffee index.coffee

This will convert all color-books/*.acb files into converted/*.json.

You will need to copy your Adobe Color Book .acb files into color-books first before converting.

Please refer to https://magnetiq.com/pages/acb-spec/.

Since the details of the license for Adobe Color Books are unclear, it is very likely that is has limited rights. Due to this IP I decided to remove all .acb files from this fork.
