It's kinda confusing sorry! So I random.org'ed the group threads (Yellow, Brown, Pink).
Then I random.org'ed the page number (Note: group players plus me were ineligible and for Pink/Brown I only random.org'ed page 300 to end because that is where it started).
Then I randomized #1-14 to determine which commenter won. So basically first found the thread, then page, then comment on page.
There were 3 items in your list. Here they are in random order:
brown
