Italy celebrated Republic Day in style on Tuesday, with aeronautics displays, speeches and memorials, remembering the day the country voted to abolish the monarchy in favour of a Republic in 1946.
Even Google joined in, with a special logo painted in green, white and red, the colours of the Italian flag.
Unfortunately, the designers of the logo failed to take into account one thing: while the plain vertical green, white and red stripes are unique to Italy, the same colours painted horizontally don't have the same significance.
In fact, the flag in the Google doodle bore more of a resemblance to the Hungarian flag.
Italian Twitter users were quick to point out the mistake.
Italy-based Hungarian travel agency Viaggi Ungheria described the gaffe as an “epic fail”.
“But is it celebrating Italy or Hungary??? You've got your flags wrong graphic designers!” tweeted @MartaGervasutti.
Ma #Google vuole festeggiare l'Italia o l'Ungheria??? Avete sbagliato bandiera, signori grafici!- Marta Gervasutti (@MartaGervasutti) June 2, 2015
But others saw the funny side.
“Why can't Google search itself for the Italian flag?” tweeted @massimo_esposti.
Ma Google non poteva fare un'autoricerca sulla bandiera italiana?- Massimo Esposti (@massimo_esposti) June 2, 2015
