MAMAMOO's leader Solar continues to tease her long-awaited solo comeback with her second mini album, "COLOURS," with the release of a mood sampler.

In the mood sampler dropped by the idol, she can be seen in the middle of a desert playing piano. Her face and music accompanying the atmosphere speak of a title track full of gut-wrenching emotion. As the video camera pans out to the beautiful yet isolating landscapes around her.

Solar's 2nd mini album 'Colours' will be released on April 30 KST.
