You want to pass several colors in one go? Use an array as the value:

irb(main):028:0> module Abc
irb(main):029:1> def self.test(options = {})
irb(main):030:2> colors = options[:colors] || [:red]
irb(main):031:2> puts "The chosen colors are: #{colors.inspect}"
irb(main):032:2> end
irb(main):033:1> end
=> nil
irb(main):034:0> Abc.test(:colors => [:red, :green, :blue])
The chosen colors are: [:red, :green, :blue]

Jesus.
