Was sind die Farben der österreichischen Flagge?

Why this is the correct answer

Austria's flag displays three horizontal bands of red, white, and red. According to legend, the design originates from Duke Leopold V of Austria, whose white surcoat was soaked in blood during the Battle of Ptolemais in 1191, leaving only a white stripe where his sword belt had been. Whether or not the legend is accurate, the triband has been associated with Austria for over 800 years.
