The flag of Spain’s dominant colors are red and yellow. The center yellow stripe is twice as wide as the top and bottom red stripes. The current flag for Spain was established by the Spanish Constitution of 1978. The red/yellow color scheme used throughout the 19th and 20th centuries was maintained, excepting 1931-1939 during the Second Republic period, when the flag consisted of equal-sized stripes of red, yellow, and purple. The current flag features an offset image of the Spanish coat of arms, representing the three arms of medieval kingdoms that would untie to form Spain in the 15th century. The flag includes the national motto of Spain, “plus ultra,” which is Latin for “More Beyond.” The phrase hints at the discovery of the New World by Christopher Columbus.
