Algebra

Hello, may I help you?
Yeah, I'm the painter. I'm here to paint the building.
Painter? We called no painter.
I wrote down the address. It's correct, right?
Well, yes.
Ok then. You want one coat or two?
No no no. I want no paint. The building is covered in mosaic tile, you see. Tile doesn't get painted.
And nice tile it is too. But that don't solve my problem, which is I got a truck full of paint you are telling me you don't need.
That is a problem, yes.
So how you gonna fix it?
What color is the paint?
Well, you got your reds, your yellows, your blues.
The tiles here are a little. . . monochromatic, I suppose.
I don't know about that. They're pretty black and white though.
Yes. Maybe a little color here and there might be. . . acceptable.
Fantastic. We'll have this place looking like Disneyland in no time.
Actually, I'm not sure that would go over too well.
No? How come?
Just a feeling.
