The 30-year-old singer said she was left in a dark place after her gruelling lawsuit against producer Dr Luke - whom she accused of sexually abusing her when they worked together, reported Contactmusic.
"This record has quite literally saved my life. I think colour symbolises hope ... I've always just found the hope in the bright colours and I wanted to bring that more into my everyday life," Kesha said.
And the singer - who released "Praying", the first single from her new album, last month - said every track on the album is personal and has helped her make it through the difficult time in her life.
