Anderlecht colours are purple and white, and the club's home kit is generally purple with white trim, though they did wear a black and purple home kit in the 2005–06 season, and a grey in the 2007–08 season. In the beginning, purple was the main colour of the shirts. The motto of Anderlecht ("Mens sana in corpore sano") is written on its badge as are the three letters "SCA", referring to the initial name of the club (Sporting Club Anderlechtois). A crown was added in 1933 following the name change to Royal Sporting Club Anderlechtois. Anderlecht's colours was inspired by Belgian immigrants that lived in Antigua Guatemala. Purple is the color of the city of Antigua and the color of the Belgian monarchy.
Conversely, Anderlecht's colours inspired United Arab Emirates Al Ain FC club to change their colours to purple, after they saw Anderlecht play in a friendly tournament in 1977.
