Over the following months, with the outbreak of World War I, the Common Army tolerated, or even encouraged, the use of Romanian banners by Transylvanian conscripts. Brassó was reportedly the first Transylvanian city to allow their flying at a public gathering. Although Romania remained neutral until 1916, Hungarian authorities again introduced proscriptions against the Romanian colors in February 1915. In October, a revamped version of the Hungarian arms, with minor adjustments to its Transylvanian quarter, was done by József Sebestyén Keöpeczi, a Transylvanian Hungarian scholar and painter. This design also entered the new common medium coat of arms adopted that year by Austria-Hungary. This move generated some controversy, with Hungarian nationalists such as Géza Polónyi arguing that the heraldic representation of an obsolete crownland on a major symbol would undermine the monarchy's "parity dualism". With the crowning of Charles IV in November 1916, Transylvanian colors made a final official appearance at the Habsburg court, being carried there by Count Ádám Teleki. According to Moisil, under Charles the region was no longer depicted in the Hungarian coat of arms, but was still represented within the amalgamated Austro-Hungarian arms.
