Singing Blue's

Okay so Peridot is a boy. PLEASE DON'T KILL ME. I support the Jamzuli ship but i have some inspiration for Lapidot.

Lapis is a normal teenage 19 year old girl. She was born with blue hair and blue eyes and pale skin. She loves to sing and play instruments. But she also suffers from depression.
Peridot is an extremely smart boy. He is 19 years old. He has blond hair and emerald green eyes and pale skin. He loves to work with technology and loves to read and write. He is not social. And he knows how to play most of the instruments.

What happens when music and writing mix together? What happens when green and blue are mixed in the same can? Will it spill or will they go to a stage and sing their heart out? Only the lyrics will tell.
