Among the colours are pink representing cancer, yellow (unsafe abortion), blue (sexual gender-based violence), red (HIV/AIDS) and purple which represents mental health.
Other colours used during the colour festival initiative are white which represents adherence, orange (lead champions for change) and maroon for people living with HIV.
As celebrations kick off, colours are displaced on a tray, and each picks their colour as per the area of interest which they paint on their faces.
The youth cheer each other during the painting, dance, sing and spray colour in the arena, challenging each other to spearhead sensitisation initiatives back in society.
During the initiative, various activities are conducted namely HIV testing services, condom distribution, and information dissemination through the peer-to-peer engagement model while sharing the minimum information package on HIV and Sexual gender-based violence.
Teenage pregnancies and mental health initiatives are also included during the festival.
"I am finding it easy learning about HIV using colours. Dances and songs also make sensitisation so interactive," says Jane Karemi, 18 years old.
Karemi also had a chance to undergo her first HIV testing in the fist.
Ms Murunga, notes that the initiative works to inspire and empower young people to make informed decisions that lead them to live healthy productive lives and be the agents of change in their families, communities, and counties.
Additionally, it aims to place the adolescents and young people as a community of practice at the centre for decision-making using the Human-centred (HCD) rather than a public-private participatory approach aiming to innovatively reach out to the youth, to identify their challenges, prioritize and come up with innovative solutions.
The colour festival is aimed at reducing new HIV infections among adolescents and young people.
It is also key in reducing cases of teenage pregnancies and reduced incidences of sexual gender-based violence.
Currently, the initiative is ongoing in Meru, Turkana and Trans Nzoia counties.
It is held in partnership with the institution's student leadership.
The peers participating in the initiative be selected from the youth networks in the county and pre-trained on the minimum information by Maisha Youth County Champions.
Maisha youth county chairs identify the respective institution's student leadership, schedule a meeting with them and identify the possible best implementation strategies.
The student body also supports resource mobilisation and planning.
