The flag of Sri Lanka, also called the Lion Flag, consists of a gold lion, holding a kastane sword in its right fore paw, in front of a dark red background with four golden bo leaves, one in each corner. Around the background is a yellow border, and to its left are 2 vertical stripes of equal size in green and saffron, with the saffron stripe closest to the lion. The lion represents the Sinhalese ethnicity and the bravery of the Sri Lankan nation while the four Bo leaves represent Mettā, Karuna, Mudita and Upekkha. The orange stripe represents the Sri Lankan Tamils, the green stripe represents Sri Lankan Moors, and the maroon background represents the majority of Sinhalese, like the lion, this is the color used in early flags of Sri Lanka by Kings.

It was adopted in 1950 following the recommendations of a committee appointed by the 1st Prime Minister of Ceylon, The Rt Hon D.S. Senanayake.
