BUENOS AIRES – A new study is raising questions about whether the original color of the stripes on Argentina’s flag was celestial blue or actually ultramarine blue.
Specialists from the National Scientific and Technical Research Council (CONICET) and Universidad Nacional de La Plata studied fibers from the oldest flag known to exist in Argentina and determined that the blue in that standard was not the celestial blue that Argentines have always considered part of their heritage.
“This particular flag had a color with blue pigmentation. There’s no doubt about that,” researcher Carlos Della Vedova told EFE.
An analysis using spectographs and chemical tests determined that the fibers were ultramarine blue, not celestial blue, the scientist said.
The flag, which was found at a church in the northern city of Tucuman, was made between 1812 and 1814 at the request of Tucuman Gov. Bernabe Araoz, Della Vedova said.
“It was made with silk that was very expensive at the time, very beautiful. It was an indoor flag, not for a flagstaff,” the scientist said.
If the analysis and historical research is correct, Argentina’s flag should have stripes the color of those on the Tucuman flag, the scientists said.
The study has been validated by scientific peer review journals abroad, but some historians and experts have criticized the findings and insist that celestial blue should be the stripes’ color.
