I can't find it in the archives forum, The only thing I could remember is the thread made by Simba '04 about suggesting new theme for Lea and one of the idea was Elephant Graveyard Green or Grey. TBH I "consider" my self as "Historian" in this forum but it seems I couldn't track the original thread in the archive section.
Maybe if someone remember about the old thread they could give us ideas and input about making more theme.
