This is 99% invisible. I'm Roman Mars.

Barbara Visser was nine years old the first time she saw it.

She was on a school field trip to the Stadlic Art Museum in the center of Amsterdam.

I guess it's about 1975.

One could say it's the heyday of that museum.

They were really at the forefront of modern and contemporary art.

The Stadlic was built to impress.

There was a huge stairway leading up to the light in a way a bit biblical

a stairway not to heaven but almost to heaven to the Hall of Honors.

The Hall of Honors displayed some of the museum's finest paintings, but one in particular

dominated the room.

The tour guide led Barbara in her class over.

And this painting, it struck me like lightning and not in a positive way.

What she saw was a massive canvas, nearly 18 feet wide and 8 feet tall.

On the left side, a small strip of blue.

On the right, a small strip of yellow.

But the rest of the surface was painted entirely red, this majestic

fire truck red. And it kind of annoyed me. I really, I didn't know what to look at, where to stare, what to do with it.

And the only thing that the guide shared with us was the title and the title is a question

who's afraid of red yellow and blue and I got very angry.

I ran out of the museum.

I sat on the steps and was determined not to go in again.
