[Chorus]
What Mary didn't know
What Mary didn't know
Didn't know, she did not know
She was a little girl
In a black-and-white world
She didn't know, didn't know

[Verse 1]
Mary took a look inside of my head
Saw me looking at the color red
Saw how my eyes worked, how they linked to my brain
Yeah, she could see it, but, was it the same?

[Pre-Chorus]
Mary'd never seen color herself
Just read descriptions in her books on the shelf
Thought she knew all about the ways that we see
But was it the same for me?

[Chorus]
What Mary didn't know
What Mary didn't know
Didn't know, she did not know
She was a little girl
In a black-and-white world
She didn't know, didn't know
[Verse 2]
Mary sweet thing didn't realize
The world around her yeah, with her own eyes
Was there more to sight than words could tell?
She could explain it very well

[Chorus]
What Mary didn't know
What Mary didn't know
Didn't know, she did not know
She was a little girl
In a black-and-white world
She didn't know, didn't know

[Bridge]
One day, Mary left her room behind
Opened her eyes and opened her mind
And she was shocked by the things that she saw
The world of color, well, it left her in awe
Mary, Mary, with your jaw on the floor
Mary, Mary, thought you knew it all, knew it all

[Chorus]
What Mary didn't know
What Mary didn't know
Didn't know, she did not know
She was a little girl
In a black-and-white world
She didn't know, didn't know
