Twelve-year-old Bulgarian singer, Gabriela Yordanova, who will be representing Bulgaria at this year's edition of the Junior Eurovision after winning the national selection in September, officially presented her song on Sunday.

The song is entitled “Cvetat na Nadejdata” (“The Colour of Hope”) and the lyrics were co-written by Gabriela and poet Ivaylo Valchev.

The song is performed in Bulgarian by Gabriela and the runner-up in the national selection Ivan Stoyanov and conveys the message of hope, dreams and happiness, illustrating the ability of children to find the colours of life.

The song was composed by musicians Slavi Trifonov, Evgeni Dimitrov and Georgi Milchev – Godji, the team behind the “Planet of the Children” song, which represented Bulgaria at the 2014 edition of the song contest.

The “Planet of the Children”, which was performed by Krisia, Hasan and Ibrahim, earned Bulgaria second place at last year's edition of the Junior Eurovision.

Krisia, Hasan and Ibrahim finished twelve points behind the winner from Italy Vincenzo Cantiello.

Subsequently, Italy refused to host the contest and the right was granted to second-placed Bulgaria.

The tickets for this year's edition of the contest, which will take place on November 21 at the Arena Armeec hall in Sofia, went on sale on Monday.

The 2015 Junior Eurovision will have the largest number of participants since 2007, with a total of 17 countries competing.

Krisia also plays an important role in this year's edition of the song contest as she performs the theme song - “Discover”.

The official video of "Discover" was also unveiled on Sunday.
