RazerBlade 14 can't control in-built keyboard lights

Okay so I have a razerblade 14 with RGB keyboard which it comes with. I really want to be able to control the lighting of the keyboard, especially in matters of colour selection. Is it possible or will the keyboard just keep showing random colours on its own? It's been barely two weeks since I've gotten this keyboard! Nothing is wrong with it... I just want to be able to control the in built keyboards lights.
