The String2color gem takes extends the Ruby String class and turns a string into a random RGB color. Since RGB has three values, naturally the string must be three characters or longer to work.
Add this line to your application's Gemfile:
gem 'string2color'And then execute:
$ bundle install
Or install it yourself as:
$ gem install string2color
'foobar'.to_color #=> RGB(54, 111, 102)
