Subject: Help on hashing multiple keys and values

I'm trying to create a hash with multiple values per key from a tab
delimited file. numbers_and_colors.txt example:

1    Red
2    Blue
3    Red
2    Green

What I need is a hash that has key 2 assigned to values Blue and Green.
Running what I have below just erases the previous key, so puts
name_hash["2"] would only show Green. Ruby example:

name_hash = Hash.new
File.open("numbers_and_colors.txt").each do |file_line|
  file_line.chomp!
  line_parts = file_line.split(/\t/)
  name_hash["#{line_parts[0]}"] = "#{line_parts[1]}"

I need this in a hash, so is there another way to go about this? Thanks
in advance to any help, as you can probable tell I only started learning
Ruby recently.
