hey adam -

  think i finally figured out what you were trying to do - sorry for not 
reading your first post a little more carefully...  try this:

hash = Hash.new{|key, value| key[value] = []}
file = File.open("hashtext.txt", 'r')
file.each do |line|
        line.chomp!
  parts = line.split(/\t/)
  hash ["#{parts[0]}"] << "#{parts[1]}"
end
file.close

p hash["1"]
p hash ["2"]
p hash ["3"]

=> ["red"]
   ["blue", "green"]
   ["red"]
