Oktoberfest? The yellow banner scrolls with the page, black and red are fixed. Nothing to see here, move on... Thx, Jay!
80 years anniversary of the start of WWII? Doesn't fit, Germany had different flag and colors back then.
That color is Orange, NOT gold. The Orange is the color for the #KickChildhoodCancer campaign.....that is featured prominently in that "gold" (Orange) banner. The Black and Red colors are staples for the top banner of the website year round.
