To use. Create a Gemfile that contains:
source 'https://rubygems.org'
gem 'spreadsheet', '~> 0.9.1'
Then pull the source file above into the same folder as the Gemfile and:
bundle install
bundle exec ruby color_ref_spreadsheet.rb
This will output a colors.xls file that can be used as a reference for the various
color symbols to use with the ruby spreadsheet gem.
