Sorry, I gave you the wrong threads. The red/blue car example appears in thread "When appropriate to violate 1st normal form". The thread begins in comp.databases with a post on 5/6/2003. The first cross-post to CDP came later that day. The first reference to red and blue cars appears in Albert Kallal's post on 5/8.
