The flag of Lithuania was adopted on March 20, 1989. The same colours had previously been used by the inter war independent state of Lithuania, but then in ratio 2:3. From 1989 to 2004 the ratio was 1:2, the same used for the Soviet Lithuanian flag.
As from September 1, 2004, the ratio was changed to 3:5.
Yellow color in the flag symbolizes light and sun, green is for grass and red represents the blood that was shed
for Lithuania.
