In my love for bitcoin while researching, I bumped on this forum, bitcointalk. While still trying to get accustomed to the forum interface, I have an interesting question to ask.

Since this forum started at about same time when bitcoin was launched, If the theme colour of bitcoin is Bitcoin Orange,Grey and White, and the name of this forum is Bitcointalk, why is the theme colour of bitcoin (orange) not reflected on the forum's interface? Why is the theme colour of the forum Blue instead of Orange?
