Catalan colors. The estelada is ubiquitous as a simplified symbol - four vertical bars topped by a star, sprayed or daubed on walls, lampposts or mailboxes all over Catalonia. These simple graffiti are most often in one basic color, either in black or red. More elaborate large pro-independence graffiti use often the red-star Estelada as a symbol. In 2016, the Spanish government prohibited football fans from bringing esteladas to the Copa del Rey final match between Barcelona and Sevilla, held in Madrid. The government applied the article 2.1 of the Law on Sports, which prohibits the display of symbols that "incite, foment or help violent or terrorist behavior." A Madrid judge overruled the ban after Barcelona complained, citing freedom of expression. Valencian nationalist Senyera The Valencian nationalist Senyera, also known simply as Estrelada, is a flag of Valencian Community that evolved from the regional flag based on the former Catalan Estelada. However, has never been used, since Catalan independence support in the Valencian community is below 0.1%. The white star version has been used by Valencian nationalist groups since the early 20th century. Some of these groups may be blaverist (Valencian separatist, as opposed to Catalan nationalist) in their ideology, especially those with more pro-sovereign positions. The oldest extant document showing this Estrelada - with a red star - is a war poster of the Valencian Left. Variations Since its creation, various Estelades, or Estrelades (such as the Andalusian, Aragonese or Galician separatist flags) have been adopted by leftist separatist movements within Spain. Some Estelades have also been used for other purposes than separatism.
