Katy Perry says her new album 'Prism' doesn't contain any ''darkness''.

The 'Roar' hitmaker initially wanted her upcoming studio collection to focus on her split from husband Russell Brand and the strong emotions she experienced when the divorce was finalised last July, but the brunette beauty changed the direction of the album a few months later and went for a brighter collection of tracks.

Speaking to MTV News, she said: ''There's not really any darkness on the record. There's definitely some textures and colours but I think I was saying that when I saw going through a different phase, but I really let that light in.''

The 28-year-old singer - who is currently dating John Mayer - felt it was appropriate to give her third studio album a title that would represent the positive change she has gone through and the therapeutic healing she's experienced.

She explained: ''The reason why I called this record 'Prism' is because I actually finally let the light in and then I was able to create all these songs that were inspired by letting the light in and doing some self-reflection and just kind of working on myself.

''I felt very prismatic because of that I feel like now I get to show these songs off and share these songs with the listeners and it's almost like I get to beam the colours that I've experienced out from me.''
