You were like a monochrome rainbow
When you're here with me, I'm filled with so much hope
All I know is this could never be a blur
If you stay by my side, then everything's alright
Keep me feeling so warm and close
A shade of what our future will become
Oh it's the moment we start over
Trying to show you, this is for sure
But there's still time for both of us
The colours that we need will start to show
Just stay a little longer and then we'll be
In a Monochrome Rainbow
So much I want to say, so much I want to do
It's not that I'm afraid, I just want you to know
I want to take this slowly and not rush it through
Just take your time, it's okay, I'll wait for you
Keep me feeling so warm and close
A shade of what our future will become
Oh it's the moment we start over
Trying to show you, this is for sure
But there's still time for both of us
The colours that we need will start to show
Just stay a little longer and then we'll be
In a Monochrome Rainbow
Oh it's the moment we start over
Trying to show you, this is for sure
But there's still time for both of us
The colours that we need will start to show
Just stay a little longer and then we'll be
In a Monochrome Rainbow (Just stay a little longer)
In a Monochrome Rainbow (We'll be in Monochrome)
