If yours is blue, it stays that way. 
If it's green, it's green for life.
إن كانت روحك زرقاء فستبقى كذلك. إن كانت خضراء
 .فستبقى خضراء مدى الحياة
Blau bleibt blau
und grün bleibt grün.
Los azules son azules.
Los verdes, verdes.
Los azules son azules.
Los verdes, verdes.
C’est définitif. Le bleu reste bleu.
Et le vert aussi…
Un'anima blu resterà blu a vita. 
Una verde, sarà verde per sempre.
Quem é azul fica azul.
Quem é verde fica verde.
Голубой будет голубым!
Зелёный останется зелёным!
