Flag of Ukraine different from flag of Lower Austria
There has been disagreement over the shade of blue used in the flag. In 2013, scholar Dmytro Malakov argued that sky blue was the correct colour, and that, according to rules of heraldry, dark blue should not be used. The Ukrainian Heraldry Society stated that this heraldry issue does not apply to flags.The flag is similar to that of the Austrian state of Lower Austria, the German city of Chemnitz, historical Kingdom of Dalmatia (now Croatia) and the Hungarian city of Pécs, but all of those flags have a darker shade of blue. The flag is also somewhat similar to that of the Malaysian state of Perlis and the English county of Durham (without the cross), but has a reversed colour arrangement, lighter shades of blue and yellow, and a different aspect ratio.
