Not sure I understand your question correctly. If you mean the 
source-code then you're looking for a syntax highlighting editor which 
doesn't touch the text at all but just highlights it.
If you mean when outputting e.g. via puts then it entirely depends on 
your output device. If it is a terminal that supports ANSII escape 
sequences then you can use them. Look for the Term::ANSIColor gem on 
rubyforge for a convenient way to do that. Plain it is like this:
puts "\e[1mBold\e[0m"
puts "\e[31mRed\e[0m"

With the gem you can do it like this:
puts "Bold".bold
puts "Red".red
(iirc)
